72HR - integrating fix for 208494

I am going to integrate the fix for bug "#208494 -Progress bar in 
Subversion wizards not visible" into release72 branch.
Bug description: progress bars were not visible in Subversion import and 
checkout wizards. They were outside of visible area of the wizard panel 
and user had to manually resize the panel to see them.
Impact assessment: it's a regression. It's highly visible and affects 
user's first experience with Subversion support because it's in the 
checkout dialog. It is also very confusing especially when the initial 
connection to a repository takes too long - user then has no idea what's 
going on (there is no indication the wizard is doing something in 
background).
Risk assessment: no risk, simply resizing the widow to keep space for 
the progress bar that will be added later.

Thanks,
Ondra
