Added more functionality to Cryptogram manager

Cryptogram manager now handles more logic. I'm gonna try to integrate
it next.

BTW: I exported an eclipse autoformat thing which can be imported so we
all have the same formatting
Starting integrating CryptogramManager into CryptogramLetterWidget
Moved more logic from CryptogramLetterWidget to CryptogramManager
Fixed shit

Did some final changes. It seems that everything works.

You guys should give this a test run before you merge.
