Created a migration which removes all reported include and require
statements.

* Cleanup doc comments
* Move most methods from migrations to AbstractMigrationDefinition

Conflicts:
	ext_autoload.php
[FEATURE] Display migration status in the report
[TASK] Refactor Migrations for better feedback

Refactored the migrations to give a better feedback.
The feedback now includes a description of the migration and a shorter
version of the indentifier.
Also made it possible to send feedback during the migration per issue
instead of at the end.
