Fixes #3131, add new auto-updating widget that displays the number of visitors, visits and actions in the last N minutes.

Notes:
  - Added visitors metric to result of Live.getCounters.

 * use a limit for the number of actions that are loaded for every visit. without a limit, the web server might crash (e.g. when there are 100K+ page views in one visit after a log import)
 * regular pagination in visitor log. (a) performance improvement: use indexes in the select query. (b) bug fix: the old logic was incorrect. in one setup, there are 10K+ visits but the visitor log only showed one full page and one page with one visit.
 * removed reference to trunk from tests read me

New config setting for tracker:

; The window to look back for a previous visit by this current visitor. Defaults to visit_standard_length.
; If you are looking for higher accuracy of "returning visitors" metrics, you may set this value to 86400 or more.
; This is especially useful when you use the Tracking API where tracking Returning Visitors often depends on this setting.
; The value window_look_back_for_visitor is used only if it is set to greater than visit_standard_length
window_look_back_for_visitor = 0

Notes:

  * Modified renderers so they would render arrays better. Before, arrays were added to DataTables and array keys were either lost or ignored, now they are rendered.
  * Fixed issue w/ JSON rendering that rendered arrays when the PHP arrays didn't have contiguous keys.
  * Augmented some exception messages.
  * Added utility method processRequest to Piwik_API_Request to ease use of the class.

overlay has two modes now: full screen with sidebar & full screen without sidebar. for now, it is only accessible via a new row action in the pages report.

because of this change, some mostly not-so-nice core-changes could be removed (mainly that's good because overlay doesn't impact as many things outside the plugin anymore):

 * disableHistory option of broadcast
 * handling for parameter overlayUrl in broadcast
 * openLinksInOverlay() method of html table
 * config option overlay_launch_from_pages_report
 * hack for data table to launch overlay from the links

other changes:

 * error message for wrong domain has nice styles and links to admin page when the user has admin privileges
 * when registering row actions, the order can be set
 * made row action style a little more compact
 * increased min width of label column a bit

 * Renaming Insight to Overlay
 * Includes a new minified piwik.js, generated as described in js/README. Please double-check whether the file is OK.
 * Servers that had the Insight plugin installed will need to delete it manually, right?

 * links in the pages report can be opened in insight instead of a new tab (to enable, use config option insight_launch_from_pages_report)
 * links containing an image should really work properly now
 * plugin description set

 * renaming menu item to "Page Overlay", putting it under Actions
 * config option to disable framed mode altogether (can be used when websites contain frame busters)
 * fixed error for anonymous user

 * links to the current url get a bubble as well
 * limit for the number of pages loaded from the API can be configured
 * ready for translation
 * url normalizer doesn't remove the hash part anymore (which corresponds to the latest behavior of the tracker)

Fixes #3080, add config option to disable trusted_hosts check, tweak many translations, modify UI to display one input w/ a label if only one trusted host is set (or if there's an injected host), set trusted host to Host if no stored trusted hosts and user is superuser, and don't use regex to check host.

Implementing Site Search tracking & reporting in Piwik core!

 * New Admin UI to customize, for each site, wheter site search is enabled. Also options to set default values to use.
 * New Reports: Searches, Searches with no result, Search categories, Top Pages Following a Search
 * to track "No result keyword" users will have to tag their site with a JS call, or add a new parameter to the search result page &search_count=X (X being zero for no result searches)
 * Reports works with Row evolution, PDF/HTML reports, Piwik Mobile
 * idaction_url is now NULLable because, Site Search records a page with idaction_name == Keyword, and idaction_url == NULL. This ensures that the Site Searches don't create "Page URL Not defined" records. 
 * updates to Tracker JS API, new function trackSiteSearch, also added in PHP tracker
 * New fields in log_visit to track searches
 * new segment, "searches" which can be used to select visitors who did a search ie. searches>0 or those who searched a lot, ie searches>10
 
 TODO: 
  * commmit integration test, TESTING, DOCS, FAQ, release, and a nice Prayer to the universe and the stars, hoping that I can code a major new feature without any bug...
  * It would be awesome to have compatiblity with Transitions so we can see, for a given site search, what are the starting pages and Destination pages
  
 Thank you for your patience Timo, 
 and thank in advance everyone for your help Testing this new feature!
