Nvu progress 20040406
The site manager is now able to browse local dirs, create new dirs, delete files and dirs. It took more time than expected because of the following problems:
- don't try to directly set the cursor on a XUL page element... The result can be sometimes weird: cursor is set but some XUL elements become unresponsive
- Windows sucks... And I found at least bug 239804 to prove it. It took me quite a while to figure out why the contents of the directory were correctly removed but never the directory itself.
