commitmonitor Code

(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

Fixed issue #121: SegFault of CommitMonitor on Windows Shutdown

* make StopThread() only try to stop the thread, not terminate it forcefully
* if StopThread() can't stop the thread in time, use TerminateProcess to 'shut down'

Fixed issue #133: Balloon tooltip includes ignored user names

Don't add usernames from commits that are ignored to the popup text.
