Added brakeman to the project.
Added Travis CI config file.
Fix for Travis build matrix assigment.
Fix for Travis CI and subdirectories.

Forgot that the Gemfile is in the admin subdirectory. This commit tells
Travis to change into the appropriate build matrix subdirectory before
doing anything else.
Updated Gemfile.lock for Brakeman.

Ended up forgetting to update the file in git as the gem was installed in the
VM and VirtualBox isn't configured yet to do a reverse rsync.
Added badges for Travis and CodeClimate to Readme.
Merge pull request #3 from Stavrus/build
