Resolve HG and Git names in ensure_dependencies.py

[matze]

When creating a dependencies file for use with ensure_dependencies.py, the Mercurial and Git repositories of each module are currently required to have the exact same basename (e.g. hg.adblockplus.org/infrastructure and github.com/adblockplus/infrastructure).
Unfortunately, a bunch of these repositories are not named the same, e.g. hg.adblockplus.org/infrastructure-puppet-concat and github.com/adblockplus/puppet-concat).

Thus, we may either extend the aforementioned script to support different repository names (e.g. using the hg: and git: prefixes again), or simply re-name the repositories at GitHub.

Renaming the GitHub repositories to have consistent names seems to be the better course of action.

I renamed the following repositories:

• puppet-concat => infrastructure-puppet-concat
• puppet-postgresql => infrastructure-puppet-postgresql
• ActionBarSherlock => actionbarsherlock
• puppetlabs-stdlib => infrastructure-puppetlabs-stdlib

It seems that infrastructure-puppet-spawn-fcgi, infrastructure-puppetlabs-apt, infrastructure-puppetlabs-firewall and infrastructure-puppetlabs-mysql are missing on GitHub, I will make sure these are created.

Created the missing repositories as well, and made sure that our Mercurial repositories are in sync. Side-effect is that these Mercurial repositories are up-to-date now, the dependency still points to a pretty old revision however.
