Small code review improvements.
Big update:
* Added the vendor (forall) to all namespaces.
* Renamed package.json to forall.json.
* Added a "MainFilesIncluded" event.
* Renamed the global "fa" function to "forall".
* Some minor improvements in code and code-comments.
Fixed a bug: Settings.json was also renamed to forall.json.
Added method: Core::normalizePackageName().
Fixed a few bugs surrounding package names.
* Package descriptor now uses a dot to separate vendor and name.
* Already gathered packages will now properly be skipped when the gatherer runs again.
Package renamed.
