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.

Use predefined messages instead of using RegisterWindowMessage()

Show notifications on the tray when new projects (for SVNParentPathList based urls) and/or new commits for existing projects are detected.

* Add trace statements
* Open the main dialog on tray-icon doubleclick

* enable all controls in the url dialog
* don't check the url in the url dialog but do that later (not implemented yet) in the main dialog or even the check thread
* add load/save methods for our persistent data

Add new dialog to edit and add URL settings.

* fix build system
* implement main dialog
