Lets you choose different Technic folders for different OSes
Made the default forge build #819
Custom Forestry configs get copied over like with Aether's "MenuAPI.properties"
Added the ability to use optifine and use custom XMX args (based on technicpack settings)
Now the launcher can automatically determine where the technic folder is
(Fixes issue #9)
Merge pull request #2 from Atex/master
