Building scripts

+ added scripts for triggering build system:
  * build.sh creates changelog entry, commit and tag. Can also push
    everything to origin
  * push.sh pushes specified version to origin
  * unbuild.sh resets changes done by build.sh
+ if you want scripts to be fully automated set DEBFULLNAME and
  DEBEMAIL system variables. Otherwise changelog could be invalid.
