- added option '-B' to osc maintainer, prints bugowner OR maintainer.
- added 'osc req help' as convenience alias to 'osc help req'.
- 'osc in' to be done. Its usage just prints a suggested zypper command line.
- Incompatible change: osc se now prints Project Package, instead of
Package Project for easier copy&paste.
- give better hint how to use osc vc without network connectivity.
- added printing of cache statistices to osc build
- implemented 'osc ls .' to take proj/pack name from current directory.
* Incompatible change: 'osc ls' now defaults to 'osc ls .',
* Use 'osc ls /' if you really want to list all projects.
* This is meant as a proof of concept. I intend to generalize this usage of '.'
for all osc commands. Feedback welcome.
