Merge pull request #15 from qehgt/master

Add keyboard support for ListBox control.
.gitignore globs for Mac.
- Added Xcode and OSX libraries.
Add missing bitmaps and fonts.
- The .gitignore has multiple "bin" exclusions which I think led to these resources being accidentally ignored.
Fixed OSX premake build.
- premake will now generate an Xcode 4.5 project that will build, link and run.
- To get this to work I link against static Allegro libraries. I copied these to gwen/lib/macosx.
- Other dependencies (freetype, bzip, z) are from Macports. Also copied to macosx.
- Made line lengths shorter: easier to read on laptop.
Fixed Allegro sample.
- Wrong main declaration.
- TextureBase constructor.
Fixed various warnings and errors.
- Function with no return value.
- Unused variables.
- Dangerous if !!

OSX and Allegro fixes for GWEN
Update gwen/Projects/premake4.lua

targetsuffix appends the specified parameter to the end of the project name.
targetextension replaces the extension with the specified parameter.

The samples look for "gwen-staticd.lib", but if you use targetextension the only thing that is created is "gwen-staticd".

Without this fix the samples won't compile when set to debug mode.
