Advanced Macros

Features:
- Added built in version comparision
- advancedMacros.isBeforeVersion( String:version [, String:modVersion])
- advancedMacros.isAfterVersion( String:version [, String:modVersion])
- Images can now be loaded from a httpRequest{} by passing the input table into
image.load()
- hud3D.newPane now has alisas for the different orientations
- XY = Z
- XZ = Y
- YZ = X
Bug Fixes:
- Various render fixes for 3D hud and textures. There are still some bugs...
- hud3D elements no longer 'jump' when you sneak or unsneak.
- "blocks:..." type textures now work again.
- use( 0 ) and attack( 0 ) cancel their actions as indicated by the docs.
- Fixed an issue where the internal task dispatcher did not wait for future results.
- Fixed getScreen().
- Fixed NullPointerException caused by callable tables (functions with built in docs).
Other notes:
- hud3D rotation transformation logic is now centralized.
- Phasing out GLStatemanager for RenderSystem
- Added a default toString() for luajava proxies.
This fixes an issue where it would say 'null' as the value name when it wasn't null.
- luajava proxies are now coerced instead of being provided as raw userdata.
This makes their functions and attributes useable.
