Description of problem:
long Category/Folder names wrap in bebop tree on admin UI, which makes them very
difficult to read.

Version-Release number of selected component (if applicable):
5.2 (not sure about 6.0+)


Steps to Reproduce:
1. Create folders and/or categories with long labels (deeply nested helps).
2. Make the browser window fairly narrow

    
Actual results:
Folder names wrap at spaces to beginning of next line (regardless of indent level)

Expected results:
Folder/Category names should not wrap

Additional info:
London changelist 36073 adds 'nowrap="1" to the appropriate td tag in
cms-category.xsl. 
UI has changed in 6.0, so I'm not sure if this bug is present there or not.
