Merge pull request #6 from Sh1mY/master

Moved contents from drawer to home activity
Changed the card selection to a context menu and changed the deck to be shown in a grid view
Now storing the CardInfo instead of the entire card class
Added a card flip animation
fixed number 3 checkbox label and prevented the soft keyboard from appearing on the numberpicker. (note that the auto formatting on save in my eclipse is messed up)
