Correct comments, added docblocks. Fixed checkModuleAvailability and getTopAuthoredClass

Konsolidate
* added various document blocks
* fixed the workings of 'checkModuleAvailability' as it needs to check for the '.hh' extension instead of the '.class.php' one of PHP Konsolidate
* changed the mechanics of getTopAuthoredClass to utilise the CoreStub detection in favour of the generated property '_dynamicStubClass'

Template
* fixed typo in initial note
+ added explicit check on HHVM version

DB/MySQLi
* all fingerprint settings are now property obtained from Config/MySQLi instead of Config/MySQL
