This update fixes the following issues for osc:
- add support to remove repositories recursively (mostly only usefull for admins)
- submitrequest: old not anymore used maintenance code got removed. It is possible now to create one request to submit all changed packages of an project in one request. Just run "osc sr" in the checked out project directory.
- disable keyring usage by default. print warning about misconfigured keyrings.
- prdiff: new command to diff entire projects
