commitmonitor Code

Clear the Subversion errors after we don't need them anymore.

Report the error too if just the log fetching fails.

Use the end revision as the peg revision.

Make sure that temporary files are removed after using them.
(I had over 13'000 temp files from the CommitMonitor in my temp folder before I noticed this. Yikes!)

* Add Exit button to quit the application
* Closing the main dialog with the red X doesn't quit but hides the main dialog
* Pressing ESC also hides the dialog
* Change the OK button to "Hide"

Make ESC quit the diff viewer, if the find window isn't visible.
If the find window is visible, ESC will first close that find window.

Only send notifications to the main window if not just the revision number changed but also at least one log message could be fetched. The revision number can change even if there are no changes to the specified URL!

Add tooltips for some controls in the url and options dialog.

Allow disabling the notification sound completely.

Add some information about what is done in the progress dialog when fetching the diff.
