Adding JRuby support to FactoryGirl

JRuby are affected by inconsistent behavior of overriding
  #respond_to? that is causing an unconditional call to
  #respond_to_missing.

  Current change does not affect MRI users in any way,
  JRuby-specific things are wrapped into the RUBY_PLATFORM
  check.

  Adding docs, modifying gemspec and travis.yml to make factory_girl to pass on Travis.

+JRuby users: FactoryGirl works with JRuby starting with 1.6.7.2 (latest stable, as per July 2012).
+JRuby has to be used in 1.9 mode, for that, use JRUBY_OPTS environment variable:
+
+```
+export JRUBY_OPTS=--1.9
+```

 Once your Gemfile is updated, you'll want to update your bundle.
