Added -V, --version to do_search.

This shows all the hard to retrieve, but 'essential' details about a
package: version, revision, srcmd5
If there is a better way some day, than digging through _history,
please improve core.py:get_source_rev()
It is a new option, only because it is so slow; the version
number should rather be in default output.
