Changes
-------------
1. Fixed a problem with relative URLs not working in the URL widget.

2. Fixed a problem that caused newly opened projects not to be added to the 
most recently used list.

3. Fixed a problem with the "Open Remote Server" panel not remembering the 
last information that was entered.

4. Fixed a problem with incorrect (old) behavior from the "New Project" 
toolbar button.

5. Improved the performance of searching in the classes tree. Also limited 
the number of search results to 100 and made this a configurable parameter. 
Previously it was hard-coded to 1000. Added a dialog to notify people that 
their search results were truncated because of this.
