spawnlist fixed row height

I've been testing the following patch for a bit today. It will cause the lists/trees in the spawnlist windows to use a fixed height for all cells which reduces the performance hit when the distance column is displayed.

Code:

This patch is great. Bascially fixed my performance issues I'm having with ShowEQ6. Not quite there yet but it's so much better.

Added to trunk for next release. Thanks!
