Update apache2 cookbook.

Required for newer versions of chef.
Remove errant file.
Update the ufw cookbook.
Add workaround for broken ufw cookbook.

See https://github.com/opscode-cookbooks/ufw/pull/7 and
http://tickets.opscode.com/browse/COOK-3528
Add metadata for the toolkit cookbook.

Newer versions of chef-solo don't load the attributes from other cookbooks
unless the cookbook has them mentioned in the 'depends' section of the
metadata. It's not clear if this is a change in policy or a regression, but
this is what we should have done from the start.
Re-add the munin recipe, to enable the firewall rules.

The ufw::recipes only checks the explicit recipes, not those included from
other recipes. Which is annoying, but hey-ho.
apache/ -> apache2/ fix in documentation
Remove dollar signs from code block - easier to copy+paste.
Upgrade to chef-solo 11.10 and use the omnibus package directly.
Merge branch 'updates'
Ensure apache listens on 80 and 443. Fixes #17.
Merge remote-tracking branch 'cyclestreets/master'
