Java version of LineRider

LineRider is a Flash 8 game and I will attempt to code a clone of it in
Java with less lag and more features.
Idk yet about making its context static or dynamic, so it may be between
both for now.
I will also probably get rid of EhCache for more performance, but as of
now, it's cool even if it's totally not suited for the job lol.
Idk if I will finish this game, but it will at least still be a nice way
to learn more about Java2D, physics and such.
