#130 - Use mvn build profiles for bcprov jars.

* For switching bcprov jars for the two Rails versions, use Maven
  profiles instead of properties. Helps when using IntelliJ as well. You
  can switch from within the IDE easily.
#130 - current_user method of application_controller is not accessible in application_helper
#130 - Fixing server_controller spec and moved server_xml_spec to new rails.
#130 - Move to Java servlet store for cookies.

This is what was used before (old Rails app). The Java servlet cookie
store is shared between the Spring app and the Rails app.

This prevents us from having to worry about JCE strong encryption issues
as well.
