Spelling fixes

"Indicies" -> "Indices"
Merge pull request #97 from MSGhero/dev

Spelling fixes in TexturePackerAtlas
Add a simple demo for FlxTextFormat

code by @MrCdk
Remove openfl include from the Project.xml files

It's already included in the include.xml, including it earlier causes issues with html5 / bitfive
PixelPerfectCollision: remove traces
EZPlatformer: fix out-of-bounds section of the tilemap, closes #98
MinimalistTD: compile fix for HTML5
PixelPerfectCollision: use FPS.currentFPS
FlxSpriteFilters: compile fix for HTML5
SplitScreen: use FlxCamera.bgColor instead of color

color is not supported on HTML5 currently
README.md: add installation section, remove contents

The installation section will hopefully clear up some of the confusion with compatibility (see #99)

The contents section didn't really provide much value, only being a copy of the folder structure. It's a pain to update.
