Merged master into this branch (What a horrible merge!)
Also fixed most Code Style Messages …

Wasn't in the mood to think much about if the amount of Bits are important for the remaining few Int32 and Int16 "Name can be simplified" messages.
Please change that or supress messages via attribute accordingly …

Also I fixed Tests as archives are now containers.

Once the remaining Code-Style messages are resolved this can be merged.
Unless of course you have some reason to wait with a merge.
