commitmonitor Code

* Only load the info data from disk when the thread starts.
* Don't save the url info data as long as the main dialog is visible.

Try to stop a possible running thread gracefully before exiting the process.

Delete all diff files when a monitored URL is removed.

Don't check projects which don't have updates every minute but only after another time interval has passed.

Trim the trailing slash from the SVNParentListPath projects name.

Canonicalize the urls before adding them to the monitoring list.

* fix regex for parsing the SVNParentPathList page
* check for html pages from inside a repository

First non-working version of parsing the html page from an SVNParentPath url.
Got the downloading part working now after several hours of trying.

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

* create the main dialog with passing a parent window
* in the main dialog, send a message to the parent window when an unread message is shown so the parent window (the hidden window) can change the system tray icon to 'normal'.
