Added a couple of things!

Added Solar Expansion support, added armor camouflage upgrade, added a
feature so that when you press shift it makes you jump normally, added a
flight speed modifier to the speed upgrade (still considering making it
a standalone upgrade) and finally changed the Solar Upgrade class a
little bit so that Solar Expansion support would be easier! (thats not
it, I still have many more plans!)
I will also maybe add Russian and Greek language localizations later! :P
