- added 'osc bugowner' as a more intelligent version of 'osc maintainer -B'

- 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.
