Remove craft.sh concept / add --task argument

There will likely be a way how a source repository can specify the
default shell commands to build itself for craft. If this will be a pure
shell file, YAML, JSON or something else is not clear for now.

This commit removes the lookup of the craft.sh file and instead adds the
--task command line argument to specify that script code.

This might only be a temporary solution but is the best fit for now.
