Need a sub-script to count contributors

[Jorge Castro]

Ubuntu features contributors of the cycle in their release notes, it'd be nice if we could have an automated way of seeing who contributed to charms.

- Needs to count every commit, not just new charms, that way we can get people who fix charms.
- Needs a way to set a date so we can figure out contributors for a given cycle
- Though not necessary, it would be nice to search lp:juju/docs too so we can mention doc contributors

Here's a quick and dirty in case I get hit by a bus.

#/bin/bash
(for i in `charm list | grep lp:charms`; do bzr log --include-merged $i |sed -e 's/ *//g' | grep 'committer:'; done) | sort -u > results.txt
