Changed the colors of the network graph to match the color of the
differents houses (the color will probably be in the database in the
future).
Reactivate the panel swipe (there are still some problems but it's
better to keep the swipe for the user).
Added various comments and fixed the missing logo in the about page when
using the phone app.
The user can now zoom in/out the network graph in the home page with
two buttons.
Added the cordova device plugin to detect when the phone is ready and
the change the behavior of the backbutton on android.
Disabled the panel left swipe because of some scroll problems in
landscape mode.
