This MR will allows us to do use erb templating syntax inside config/database.yml

Example:

<%
  # http://mislav.uniqpath.com/rails/branching-the-database-along-with-your-code/
  app = "noosfero"
  branch = `git symbolic-ref HEAD 2>/dev/null`.chomp.sub('refs/heads/', '')
  user = (`whoami`).gsub(/\W/, '')
%>
development:
  adapter: postgresql
  encoding: unicode
  database: <%= "#{app}_#{branch}_development" %>
  template: template0
  username: <%= user %>
  password:


Did not break any test that was passing before:
