Changed markup to match bootstrap v3

The markup was still matching the bootstrap v2 classes thus it looked
pretty shitty.
Created project "framework" and moved business logic there

Warning: Does not compile.
The Code does not compile but I had to commit it anyways to not lose any
data.

Moved business logic to project framework and started refactoring a
whole bunch of classes. Refactoring included removing all occurrences of
the muscle_log.util.DB-Object which should not be used anymore but use
the EF Context instead.
