commitmonitor Code

Add an options dialog.

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.

Fix compiler warnings.

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.

Handle the WM_TASKBARCREATED message.

This is a bigger change:
* only use one instance of CUrlInfos
* pass around that one instance to wherever it's needed
* guard the data in CUrlInfos with critical sections
* make sure the data is guarded only for short times
* in the monitoring thread, use a copy of the CUrlInfos data because of the point above

Keep track of the main dialog shown. If it is shown while the thread is running, discard (do not save) any change in the url data which the thread might have done.

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

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