commitmonitor Code

(Closes issue #169): Cannot select a project in the project pane using rigth mouse button

* select the right-clicked item before showing the context menu
* restore the previously selected item after showing the context menu

(Closes issue #165)
Allow the IDOK message if the ALT key is pressed even if the button doesn't have focus.

Remove the "mark all as read" context entry for projects, only show that entry for SVNParentPath entries.

Closes issue #153
* use the accelerator table in the main dialog
* extend the accelerator table
* handle the ID_POPUP_MARKALLASREAD command in the main command handler

Fixes issue #123
* add boolean state to the CUrlInfo class
* add context menu for the tree control to enable/disable monitoring
* show a gray icon if the project is not currently active (i.e., monitored)
* skip checking the project if it's not monitored

Fixes issue #147:
Check for the process name to be CommitMonitorLocal.exe, and if it is (instead of the default CommitMonitor.exe), save/load all data in the same directory as the application exe file is instead of %APPDATA%\CommitMonitor.

code cleanup:
* rename CRegStdWORD to CRegStdDWORD
* replace the stdstring defing with a typedef for tstring
* get rid of the wide_string typedef, use std::wstring instead

Move the filter box one pixel down.
Update issue #75.

When adding log entries to the list control, only add entries that match the filter string.
This fixes issue #75.

Update issue #75:
* add label and edit box for filtering
* handle resizing/repositioning of the two new controls
