Initial commit for the Overseer project

This commit adds a working version of the overseer project.  You have to add AWS
credentials to your environment, or manually to the aws_utils class for now.

Unit tests will also most likely ultimate fail if run.
Adds the --sync option

Adds the command line option --sync (-s).  By default overseer will now just
show you the changes and only sync them if you specify the -s switch.
Merge branch 'master' of github.com:brianbianco/overseer
