BitBake Shell
General Question to be decided: Make it a full-fledged Python Shell or
retain the simple command line interface like it is at the moment?
TODO:
* readline completion (file and provider?)
* specify tasks
* specify force
* command to clean stamps
* command to reparse one bbfile
* automatic check if reparsing is necessary (inotify?)
* bb file wizard
* call editor on bb file
* clean-and-rebuild bbfile
