Updated build script

I changed the build script from the LeagueLib build to a build script
for my own use. It is completely different because it is being used now
to build LoLStatTracker. I included some of the resources that also go
into making the executable. Additionally, I included the missing Twin
Shadows icon
Non-development environment updates

I made some changes due to resources not being found when running
LoLStatTracker anywhere that wasn't eclipse.
