Description:
Add per-file copyright headers

As requested during the release process for Ubuntu, we need a copyright
statement at the top of source files. I have deliberately excluded
documentation and non-go code for now, pending feedback. Because bzr
already
has a fancy tool for doing the years from the revision history, the year
stated
comes from there rather than being project-wide.

The changes in this branch were generated using the following script:

	#!/bin/sh
	set -e
	L1=" Copyright 2013, Canonical Ltd.\n"
	L2=" Licensed under the AGPLv3, see LICENCE file for details.\n"
	find . -name thirdparty -prune -o -name "*.go" -print0|xargs -0 sed -i
-e "1i//${L1}//${L2}"
	#chmod 755 scripts/release-public-tools/release-public-tools.sh
	#find . -executable -type f -print0|xargs -0 sed -i -e "2i#${L1}#${L2}"
	#sed -i -e "1i#${L1}#${L2}" scripts/jujuman.py
	bzr update-copyright

Note that I've not included the logic for adding the header to python
and shell
scripts when creating this branch. There are only a few of them, and
making the
output pretty in an automated fashion is harder.
