Add mysql2 to the project so we can use the mysql database already on tapasdev -> update database config and add a staging environment config file.
Update fedora/solr to just point at dev in the staging environment.
Adds a config file for api key info and and a tapas_rails thor namespace with a simple task for loading an environment dependent user.  Since we assume that nobody cares about the development user's password and api_key those are just in the config file.
Add staging environment credentials to the tapas_api config.
Add Capistrano gems to project, update config/database.yml, add deploy scripts.
Update config/redis.yml to define a staging environment.
Spaces instead of tabs inside exist.yml
Eliminate vagrantfile/provisioning for tapas_rails -> can't imagine it'll be run in isolation (no plattr) very often.
Update revision for cerberus_core.
Add staging environment to exist config.
Update tei_metadata_extractor to return no date instead of a technically invalid string -> update tests accordingly.
Merge in development changes.
Actually read the file before trying to parse it.
