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 compare the stats of multiple characters with two
graph (column graph and polar spider).
Small refactor of the displayPolarSpider function to work in all pages.
