(svn r3674) -Feature: [OSX] Added support for tripple binaries (binaries optimised for G3, G5 and i686)
G4 have no problems using G3 code while G5 can, but really benefit from getting their own optimised code (Apple: G5 is not just a fast G4)
Also changed FAT_BINARY to UNIVERSAL_BINARY since Apple removed most (all?) references to fat binaries on their homepage two days after I added FAT_BINARY

(svn r3673) -Codechange: [OSX] changed the makefile to autodetect if it compiles on G5 and then adds flags to optimise for G5
This will not interfere with crosscompiling or universal binaries

(svn r3672) -Fix: [makefile] fixed bug where some settings where overwritten with the default ones when MAKEFILE_VERSION was changed

(svn r3671) -Code cleanup: fixed style and removed commented out code in video/cocoa_v.m

(svn r3670) -Codechange: [OSX] rewrote a part of the cocoa video driver to speed it up by 1000% in fullscreen
rewrote QZ_DrawScreen to only redraw dirty rectangles (instead of everything)
This reduce the OpenTTD time spent on this function from 75% to 6,7% (in main menu)
Note: window mode is unaffected by this commit
Note: the mouse pointer can now leave artefacts in debug mode
