Most of the code dealing with the LogTypes namespace was C which lead to a lot of nonsensical casting, so I have dumbed LOG_TYPE and LOG_LEVEL down to plain C even though the move of wiiuse into Source means we don't currently call GenericLog from C. Set logging threshold to MAX_LOGLEVEL at startup so debug builds will also p rint debugging messages before the GUI is running. For some reason the way we use SetDefaultStyle doesn't play nice with wx 2.9 so we just get the default black text on a black background. Using a gray background works around that problem, but I found it to also be much easier on the eyes so I have switched the background color on all versions. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6528 8ced0084-cf51-0410-be5f-012b33b47a6e
