[TxMt] New Folding Icons (and Bookmark Icon)

Hello everyone. I tweaked the folding icons again. Still using the Stoplight color metaphor, but made them a little less saturated and a little smoother around the edges. I made the Bookmark Icon blue too. Attached is a screenshot and the required PNGs.

To install: 1. control-click on TextMate in the Finder and select "Show Package Contents" 2. double-click on "Contents" in the window that opens 3. double-click on "Resources" 4. copy my replacement pngs to this Resources folder. Accept the dialog to replace the existing pngs.

Feel free to add this to the wiki.
