commitmonitor Code

Update issue #462: add support for default credentials (username+password in Options dialog, checkbox in Project/Url dialog)

Add a button to the options dialog which opens the example who-is-who.txt file for editing.
If the file does not yet exist, it is extracted from the resources and saved to the correct location.

Patch from Björn Carlsson:
New option to scroll to earliest unread item, when project is selected

Move CommitMonitor.rc and resource.h one dir up where they belong.
