This was based on the idea that the interfaces should remain static. I hope this change is enough to ensure stable interfaces until release 1.2. Overview of changes: Moved all interfaces into the same dll. Encryption and compression is now plugable modules, just as the backends. Encryption/compression can now register an UI. Encryption now uses AESCrypt as a default. GPG does not default to using the --armor option. Added support for generic modules, but none are written yet. Added support for plugable settings pages in the "Options" dialog. Fixed issue #148. Duplicati now uses AESCrypt as the default encryption format. Fixed issue #199. GPG now supports custom commandline options. Fixed issue #207. Encryption modules are now plugable. Fixed issue #118. S3 credentials are now stored. Fixed issue #151. Backends can now register system wide options. git-svn-id: https://duplicati.googlecode.com/svn/trunk@427 59da171f-624f-0410-aa54-27559c288bec
