Root password for hostname for local_action

[solomongifford]

Related to #22, if local_action is used with a mysql install ansible_hostname is localhost and not the hostname of the machine and the root password is not set.

Suggestion would be to grab the results of:

command: 'mysql -NBe 'SELECT Host from mysql.user WHERE User = "root" order by (Host="localhost") ASC'

Note that this orders the localhost last so that ansible doesn't lock itself out.

Nice. Silly me, trying to manipulate the result set with Python/Jinja2... when just adding the order statement to the MySQL statement would work perfectly.

This should be simple enough to do—thanks for reporting, and I'll try to get to this soon!

Fixed in PR #28.
