minor updates (F10 cmdline, !ExportDuplicateTiles, !RunCMDLine, tutor.html)

[mgarcia-org]

Hi Mike, Sorry for bothering you again... just letting you know I've made some minor updates, not sure if you're interested in them? The removal of duplicate tiles was an issue for me, because I also needed StartWithEmptyTile, anyway I called it !ExportDuplicateTiles

Added F10 on the command line, so it exports the project and exits, ie when called from makefile

!RunCMDLine - runs a cmd after it finishes correctly (tested working in winXP and win7)

And updated your tutor.html from your TS website and added the above at the bottom.

Regards Mike
