commitmonitor Code

Fix compiler warnings.

Use predefined messages instead of using RegisterWindowMessage()

* use a better, reentrant reader/write section class
* refresh the UI in a timer interval

Block the custom draw handler of the list control while the control data is updated/changed.

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

Implement resizing the log message view.

Remove the variable m_bThreadRunning from the main dialog: the main dialog doesn't have a thread.

Put all urls which are part of an SVNParentPath below the tree node of the SVNParentPath entry.

* 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'.

Implement deleting of log entries.
