Highlight differences on both sides. Show the accelerator subregs in order. Make it possible to include some code from Dolphin into DSPSpy, good for grabbing useful #defines. (had to change the GEKKO log to POWERPC). git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3120 8ced0084-cf51-0410-be5f-012b33b47a6e
