refs #4141

Added namespaces to functions.php files in the five plugins that had one
Work in progress

renaming Unzip to Uncompress,
Renaming Tracker/Referer to Tracker/Referrer,
and few more

Removed many Piwik_ functions, in Piwik 2 it is best practise to use the methods calls instead

Todo: finish converting core/ classes + convert plugins/ classes to use \Piwik\Plugin namespace + fix build + Merge master

Refs #4059 Work in progress: Conversion to use Namespaces: Period*, Metrics, Segment, SegmentExpression, PluginsManager.
Removed some deprecated code.

Converting Access & Auth to namespace

Notice that auto refactoring has created a nested namespace. Not sure this is what we want - so we might have to edit those nested namespaces afterwards (I think they don't look so good)

2 steps required:

1. Refactor > Move > \Piwik\Core\Config (uncheck "Create new File")
2. Refactor > Rename > Piwik_Config to Config

Implemented custom event dispatching system for Piwik (replaced event dispatcher lib in libs/Event).

Notes:
  - New dispatcher can execute callbacks before or after other callbacks.
  - It is also possible to dispatch events only to a specific set of plugins instead of all plugins.
  - Moved Piwik::unprefixClass to Piwik_Common::unprefixClass
  - Added visibility to some event handlers that were missing it.
  - Allowed two unit tests to fail w/ better diagnostic messages.

Introducing new PluginsArchiver class. Plugins can create an Archiver inheriting this abstract class.

 * new segment 'siteSearchKeyword'
Fixes #3903, #3905:
 * adding few fields in the Live API output to accomodate getSuggestedValuesForSegment
 * renamed other fields for consistency with segment names
Fixes #3906:
 * new API: getSuggestedValuesForSegment which returns top suggested values for a particular segment. It uses the Live.getLastVisitsDetails API to fetch the most recently used values, and will show the most used values first

 * Adding tests for everything. The test case actually generates data for all segments so that VisitsSummary.get returns some data for each of the 47 segments being tested returns some data.
  How it works:
  * generate extended data in fixture
  * Tests (1) call getSuggestedValuesForSegment for each segment, check there is some data returned for each segment
  * get the first suggested value from the list,
  * Tests (2) call VisitsSummary.get with this segment value, eg. countryCode==ru.
    * I worked this way for all 47 segments until all tests had some data ==> now we know that all segments have been tested and that the auto suggest works for all segments. TDD FTW!

Refs #2908, refactored tests so database setup (adding sites, tracking visits) are separated from API tests. Put setup code into fixtures and reused code as much as possible.

Fixing PrivacyManagerTest (?) by disabling the data purge when we import the test data (or the purge deletes the data a bit too early (during test setup))
