changed the scaling value to improve visual look
Added new font effects sample along with new MOAIFontEffectsShader added in the shader mgr
merged in documentation support changes from develop-new
got rid of warning in dynamic glyph cache and text style setPadding () func
Added shaders to the font effects sample and text outline is implemented but has a bug where there is an outline on the left edge of the glyph. Also commented out code in MOAIShaderMgr, will properly add the shader in the future.
