Also, some tab/space mismatches removed from VideoOGL, and some places I missed in VideoDX[number] projects.
Now, the Core is literally the only project with tab/space mismatches (on a large scale).
Also fix up the dangling else's. Shit just looks incredibly ugly in terms of actual structure in the code.
I took the liberty of adding comments in FifoPlayerDlg.cpp, LogConfigWindow.cpp, LogWindow.cpp, and FrameAui.cpp to better explain some things.
If any comments are wrong, don't hesitate to complain.
