#130 - Making bouncy castle toggleable.

JRuby 1.7.11 needs bcprov-jdk15on-1.47.
Older JRuby continues to use bcprov-jdk16-140.jar.
pom dependency is left behind, temporarily, since it is needed at compile time.
#130 - Started Rails 4 app.

Steps taken:
* Install rails 4.0.4 externally using an rvm gemset.

* Create a new rails project:
  cd server/webapp/WEB-INF
  rails new go --skip-bundle --skip-active-record --skip-javascript --skip-test-unit
  mv go rails.new

* Remove everything except rails '4.0.4' from rails.new/Gemfile

* Install required gems into rails.new/vendor/bundle:
  cd rails.new
  ../../../../tools/bin/go.jruby -S bundle install --standalone --path vendor/bundle
#130 - Configure Rails 4 app.

Bundler is loaded specifically, in boot.rb.
Remove config of unused parts of rails.
#130 - Fix Felix to work with JRuby 1.7.11.

Felix adds a URLHandler to the URL class of Java, which causes
JRuby to fail to load any JARs inside its jruby-complete-1.7.11.jar.
