commitmonitor Code

(Closes issue #152) : Use Snarl popups
* include the snarl API
* use snarl to show a popup if it is running, otherwise still use the CommitMonitor popup as usual
* include the png resource in the installer for snarl to use

(Closes issue #183) : Monitored project changes to a folder with several subdirectories
* use the last checked revision as an additional check

(Closes issue #161)
* add option for showing the context menu on a left click on the tray icon so the user can disable this.

Show the tray menu for left clicks too.

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

Closes issue #91
* add error number parameter to CUrlInfo class
* when an error happens, save the error number
* before checking a repository, check the last error number and prevent the check if the error was SVN_ERR_RA_NOT_AUTHORIZED until the user cleared the error

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

Fixed issue #136: Animated icon doesn't clear after network issue is resolved
