WinGui:

WinGui:
- Activity log - Added CPU description, temp dir, install dir and data dir to the WinGUI log header.
- Renamed rssReader to appcast reader
- Added option for stable builds to check unstable appcast.
- Unstable builds check both appcasts so will always show the latest release
- Added some containers to frmMain.
- Fixed (I think) an issue with a regex which prases the CLI version information. It may not detect public release build information up correctly.
