Initial Xcode 4 templates for SDL/Mac 1.2 and 1.3. The major difference between the two is SDLMain. Copy all templates to ~/Library/Developer/Xcode/Templates/SDL or /Library/Developer/Xcode/Templates/SDL Templates based off information documented here: http://blog.boreal-kiss.net/2011/03/11/a-minimal-project-template-for-xcode-4/
