New tools, toolbar buttons etc.
The red builder brush is now solid lines instead of dotted. (the campaign to bring back the dotted line starts here!)

There are now things about that look like brushes but aren't.
- brush scaling is now a dialog box

Birelli: I started a tutorials section, but on second thought this page should probably just go in its entirety and move everything into "new features in UT2003" (along with the scripting page). And then just make a subpage off of that called something like "UT2003 Mapping" with content from this page and more.
