Getting the options ready!
Began work on styling options drawer
Added methods for building the options drawer

Changing something in the drawer also updates the appropriate option in
the local storage.
Added common.js to include all common functions, worked out showHidden option

Apps now deal with the "Show hidden apps" option by showing a grayscaled,
faded out version of the app icon in the Apps list. The context menu for
such hidden apps will also have "Show app" instead of "Hide app".
Put in the options button to open the drawer, and drawer-opening functions.
Bumped version number
