batch file that does the whole tmThemes dir

I had this file for an older version and I never sent it in, but I figured I should ;-)

It just runs the colorSchemeTool on the entire tmThemes dir, so you don't have to edit the run.sh file. 

It also redirects the colorSchemeTool output to a file (colorSchemeTool.log) instead of displaying in the terminal. 

Thanks for releasing the colorSchemeTool and everything else!
