Made clear how to make the precommit hook

There is a pre-commit hook set up step in the docs that references
a relative path. A line exemplifying where that command is run from
has been added to address the frequent question of "what is this
relative to"

environs/sshstorage: fix intermittent test failure

The initial "bash" command was changed at some
point from being all-on-the-command-line to bash
executing a script on stdin. The test changes to
reflect that.

Fixes https://bugs.launchpad.net/juju-core/+bug/1323898
Merge pull request #9 from dimitern/500-add-networks-constraints

state/constraints: Networks constraints added

This adds "networks=..." constraint in the constraints
and state packages. The ability to specify networks
to include/exclude when selecting a machine to deploy
a service's unit with specified constraints. Both
positive and negative entries are supported and the
value of "networks=" is a comma-delimited list of
(juju) network names. Negative entries have "^" prefix.

Examples: networks=logging,^db,storage,^dmz

Means: use machines (if possible) on the "logging" and
"storage" networks and not on "db" or "dmz" networks.

No changes to cmd/juju/deploy or other commands yet,
this will come in a follow-up.

Merge pull request #4 from perrito666/contributor_doc_updates

There is a pre-commit hook set up step in the docs that references
a relative path. The usual confusion is because the relative path
in ln is relative to where the link is created not to the current
path and therefore people thinks they have a folder missing.
A line exemplifying where that command is run from
has been added to address the frequent question of "what is this
relative to"
