Reworked encryption to not support streaming, but only pre/post process encrypted files. The Get/Put methods in the BackendWrapper now automatically writes/reads from the signature cache. Introduced a DoubleClickRadioButton for use on the main pages. Fixed a bug where zero byte files would throw an exception on restore. Fixed a bug where deleting a folder while building the filelist would interrupt the backup. Fixed issue #17. Fixed issue #22. Fixed issue #38. Added the commandline option to support issue #39, but still needs a UI entry. git-svn-id: https://duplicati.googlecode.com/svn/trunk@131 59da171f-624f-0410-aa54-27559c288bec
