Updated some things

- Made boot gui show the boot canvas (however it is upside down...)
- Made the fullscreen textured quad display FULL screen, instead of to
the screen size of Project-Utopia
- Updated entity classes
- Updated game container. GameContainer now collects information from
the game before init.
- Updated sound manager
- Added new bootstrapping functionality. Looks for bootstrap.txt in the
classpath root, then loads the class file defined inside.
- Added new Base64 properties encoding system (allows you to create your
own properties files that cannot be edited without extra work)
- Added LWJGL file downloading (currently downloads from my skydrive,
however I will add a function to download the latest LWJGL binaries and
extract them into the classpath.
- Added an eventbus system
- Added a Checkbox to the gui system
- Added the base class for a slider to the gui system
- Added the classpathmanager (from nearly all of my other projects)
- Added the downloader (from nintendofan9797-Core)
- Added the string helper (also from nintendofan9797-Core)
