Trial->Paid conversion tracking with GTM

* Added trial to paid conversion tracking with GTM
* Removed WHMCS roundtrip from Showbuilder
* Moved all Analytics code into common/GoogleAnalytics.php
* Added a new Thank You page after plan changes to capture conversions
* Added a ConversionTracking plugin to facilitate that
* Also backported some minor staticBaseDir compatibility changes
* Fixed a logic error in creating the baseDir
