Eric Wing to Sam
Lots of fixes.
Fixed missing power management building.
Added template icons to the project templates.
DocSet stuff
Documentation fixes..
Fixed all the SDLtests. (Lots of tedious work.) It now depends on the static library target for convenience so I am not going to remove it from the SDL xcode project.
