Fixed a bug where non-modified files were marked as deleted. Cleaned up the ListContent method to use the same code as the Backup method, this closes #31. Added a WEBDAV backend for #28, but there is no UI for it yet. Made most of the work for documenting commandline options, #14. git-svn-id: https://duplicati.googlecode.com/svn/trunk@123 59da171f-624f-0410-aa54-27559c288bec
