Fixes #6664, when replaying logs in log importer, use extra information present in Piwik URLs to determine visitor ID when distributing hits among recorders. If IP is not good enough indicator of visitor, this will increase accuracy of replayed logs.

removed build script as it's now on its own repository https://github.com/piwik/piwik-package/issues

fixes https://github.com/PiwikPRO/plugin-EnterpriseAdmin/issues/4 and #6584

Refs #6513, make sure archive.php can be run w/ php-cgi (remove regression that caused it to fail) and add system test to catch future regressions, if any.

Moving CronArchive token auth check to archive script since it is only for when the archive.php script is invoked from a web request.

refs #5940 moved files into a subfolder framework, added autoloader to remove duplicated code to load autoload.php and to be able to register more autoloaders (eg for test files) on demand. This I got read of many includes that had to be updated all the time and that had to be updated all the time when moving iles

refs #6231 When a line is for a file with a known download extension and the user has specified --download-extension,
then any file with an extension not in the list will see its log line skipped

refs #4996 php tests are there, we cannot test segments auto suggest yet as they have to be returned in Live API which will be v2

refs #4996 there is a difference between link tracking enabled and installed. When replacing the initial link urls link tracking might not be installed yet but enabled (will be installed on load event). When a click is happening on a content block we still need to use linkTrackingInstalled since then the credirect/tracking request is actually happening and we need to know whether outlink/download will track it or whether we have to do it separately. Make sure to call enableLinkTracking before trackContentImpressions although there should be no huge difference as both will be delayed until ready/load event anyway

refs #4996 tests should now work in case Piwik is installed in a subdirectory although could not really test it. Also encode redirect uri

refs #4996 in case we are in an overlay session we should not track. Check could be maybe moved to trackCallback in general?

refs #4996 on hover display an image in case it starts with https?:// and ends with jpg, gif, png or svg

refs #4996 we have to add build a fully qualified URL of the content piece in case we detect the URL of an image, video or audio, pdf, ... automatically. Otherwise we cannot display a preview in the UI and one would not know which URL was actually meant. Thinking about using //domain/path instead of http://domain/path as it would track different content pieces for http and https otherwise

refs #4996 some fixes, prevent JS errors on FF<9 and IE6, add random string to piwik.js to prevent caching sometimes

refs #4996 fix js error on IE6-IE8 because indexOf is not defined there. also added removed update script again
