commitmonitor Code

Only change the tray icon back to normal when showing unread messages.

Make the icons a little brighter.

Use the icon for the diff button for the diff viewer too.

Only fetch the log messages of new commits, not the new commits including the last already fetched one.

Refactor the COMMITMONITOR_CHANGEDINFO message into two separate messages, one to save the changes and one to change the tray icon.

Tweak comments.

Reset the variable containing information about the main dialog having removed an URL before showing the dialog again.

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.

Scroll sideways in the diff viewer on shift-wheel.
