commitmonitor Code

Don't add new URLs in the thread if in the main dialog an URL was removed.
Without this, there's a race condition if the main dialog removed the URL while the thread is still running, then the thread could re-add the same URL again and 'overwrite' the users choice to remove the URL.

Give the thread more time to quit before killing it.

* Delete the temp file before writing to it to make sure that when we read it later it doesn't contain old or illegal data.
* Save the name of the SVNParentPathList 'project' into a variable since we can't use the data from the iterator: the iterator is invalid when we need the project name.

Show the authors of the commits in the notification window text.

Remove debugging code.

* change the tray icon to 'modified' when a notification is shown.
* Only update the 'last checked time' when the item *really* was checked.

* use the correct icon for "show diff"
* Only change the tray icon if really something has changed, not every time the data needs to be saved.

Use different regex to also parse modified SVNParentPathList pages (modified by using the xsl file).

Fix compiler warnings.

Use predefined messages instead of using RegisterWindowMessage()
