GSModeSelector v0.23t(2010.01.02) by doctorxyz and dlanor

- Added a coloured border for the entire GUI screen
- Corrected code indentation for large parts of the 'main' function (from OSD to PAD stuff)
- Added outline rectangle to the screen edges in OSD section
- Corrected MAGH/MAGV scaling (for GUI only) of various new vmodes
- Removed duplicate vmodes differing only in MAGH (only affected GUI)
- Removed duplicate vmodes differing only slightly in screen centering
- The above eliminated a total of 11 vmodes, leaving 31 in the program
- Corrected description of PS1 modes to show that those HDTV modes are only temporary, and will be changed to PAL or NTSC mode when the PS1 game starts, thus tricking the PS1 driver into enforcing PAL or NTSC mode, by first trying to enforce an HDTV mode. This means that it can be useful to set these modes even with a TV set that can not display HDTV modes, provided you can start the game 'blindly' (exit to uLE and use a shortcut button for "PS2Disc" command).
- Changed NTSC and PAL display offsets (yet again) to be optimized for quality direct-video cables (SCART or Component) rather than the crappy composite cables. (Let the 'flame wars' begin...) Since this is a program intended for people who want improved viewing, optimizing for worst case cables makes no sense...

NB: v0.23t is based on a number of intervening beta versions, not detailed here.
Some of the changes included require that you delete your old GSM.CNF, before saving a new one, as the some of the CNF content has been redefined. The old CNF files will jhave no effect on the new version, but you need to remove them before saving a new CNF.
