Switch from Berkshelf to "Messhall"

[temujin9]

We need a better cookbook manager; Berkshelf is helpful, but ultimately too divorced from our work flow. There don't seem to be tool-sets that suit our needs better; time has come to write a custom one.

A Messfile replaces the Berksfile, with a much shorter format which allows wildcard matches within a repository:

cookbook :source => 'git@github.com:infochimps-labs/ironfan-pantry.git', :pattern => 'cookbooks/*'
cookbook :source => 'git@github.com:infochimps/ironfan-enterprise.git', :pattern => 'cookbooks/*'
cookbook :source => :local, :pattern => 'org_cookbooks/*'
cookbook 'runit', :source => 'git@github.com:opscode-cookbooks/runit.git'

Rake tasks establish the development environment, and synchronize them with the repositories they include. Each pantry is subtree squashed into vendor/[repo], which allows for commits to be subtree selected back to the pantry. Those cookbooks are symlinked into cookbooks/[name], providing a simple interface for knife cookbook upload. That folder is further symlinked to environments/development/cookbook, for later use with refactored environment code.

Expected tasks include :

• rake ensure_messhall - establish or pull vendor folders, establish symlinks to and from cookbooks
• rake sync_messhall - given commits against the vendor folders, subtree split them to their upstream pantries
