New deck module

I've just finished the new deck module, that is now very reactive.
Some interface modifications to make navigation clearer.
To Do : Stats module, "1st hand Simulation" module, and perhaps a deck view with card thumbnails.

I'm currently working for my exams, to be Math Teacher, so I won't be able to package a 1st public version before 1st or 2nd of April in theory. Sorry about that, but I code everyday a little bit of lines... please be patient.
