Added a nice icon to the OSX port. Optimized SVG included.
- Fixed problem with iPega PG-9017 dpad. It sends AXIS_HAT_X / AXIS_HAT_Y motion events so we need to handle those if their returned axis values are nonzero.
Clarified text for iPega in supported gamepads faq.
(nit) also closed a parenthesis in the Red Samurai text :-)

Fixed iPega dpad issues
(Apple)Add a very rough draft (for backup purposes only)  of a structure to be used to generate the setting menus.
(OSX) Rough first draft of OSX preferences menu. Opening it may break any running game, and the options themself don't work anyway.
Add HAVE_NEON define preprocessor rule for performance.c
(OSX) Use NSOutlineView instead of NSMatrix for settings
(GL) Log vendor/renderer
