Removed obsolete versioning files
Added "ignored" packages; refactoring

- Added documentation
- Refactored classes
Temporarily ignored "eAlarm" because it references another job which is a little critical

It should instead reference "Shared" for the reference to the
MailingEntryObject. This is subject to change the next weeks anyway, but
until then, this package is temporarily ignored.
Refactored install procedure, added documentation
