commitmonitor Code

- Reverted revision 443: With this fix no new repositories will be found by CommitMonitor in a directory structured svn repository (multiple repos).

(Closes issue #2) : Add export/import conf file support
* add class to encrypt sensitive data in the exported file
* add class for ini files
* add new dialog to enter a password for encryption
* add exporting/importing functions to the CUrlInfos class

(Closes issue #185) : mark all as read action

(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
