[SVN] r6076

[Chris Thomas]

• Add action/context menu to the toolbar and table view
• Move "svn ls" code to SVNClient, simplify it, and tie it into the observer
• SVN nodes only see the SVNClient and never talk directly to the browser controller
• Consolidate busy wait indicator toggling
• Use a single per-browser task queue
