Minor refactoring, proxies created, mod now registers as a valid mod in Forge.

The package memorypenguin.modularmachines no longer exists as such, its contents are now inside memorypenguin.modularmachines.common.

+ CommonProxy - The serversided proxy.
+ ClientProxy - The client's proxy.
* ModularMachines - Added pre-initialization, initialization, and post-initialization methods.  The mod's instance can be accessed via ModularMachines.instance after preInit has been called.
* Reference - Updated version number, added proxy location references.
