Title: Fix some bugs/crashes in 1.7 port

This pull request fixes some crashes that occurred when I was testing ProjectRed in mc 1.7
A summary of fixes is as follows:
* Compatibility Module
* CompatibilityCorePlugin fully implements IFMLLoadingPlugin
* Compatibility plugins now use 1.7 API's (Except Thermal Expansion which is not yet updated)
But are commented out until there is a stable 1.7.2 release for those mods
* GUI Fixes
* openSMPContainer class cast exception
* The algorithm GUILib.createGrid was wrong
* Widget windows were not centered
* Esc key did nothing
* Backpacks did not load items
* all MultiTileBlocks were listed as a single block in creative tab
* Rendering
Note: I have not fixed many rendering bugs as I know you're working on that
* Null point exception when rendering machines
* array out of bounds when rendering caged light inventory items
* Null point exception when rendering logic gates
* Infinite while loop when generating caves
* power wires had a null item (they loaded before transmission proxy had init)
* Could not remove items from backpack when backpack slot number == hotbar slot number

Also, I have merged branch master into 1.7-port. (Better do it earlier than get merge conflicts later)
