add tests for ruby-debug gem in Gemfile and make sure that ruby-debug19 is used as long as RUBY_VERSION > '1.9'.

If passed "foo", a gem "foo-rails" is added to the Gemfile
and "foo" and "foo_ujs" are required in the application
JavaScript manifest.

Prototype and Scriptaculous are no longer vendored, but provided by prototype-rails from now on, also the -j option of the application generator is removed

More will come for jruby app.

That means if you don't like the new syntax, you can pass --old-style-hash to force Rails to generate code with hash rockets.

The new hash syntax of Ruby 1.9 looks more superior, so we decide to switch to it in the places that appropriate.

Test non zero exit code and that a message still appears when generating inside an existing Rails directory.

Unfortunately, I can't find out how to suppress its output so we see ....Invalid application name test. Please give a name which does not match one of the reserved rails words.....................................

dragdrop was tested twice and effects.js was missing, added checks for controls.js, dragdrop.js and effects.js to another test

Remove integration tests and ActionModel/ActiveRecord calls from 'rake plugin new' generator, it shouldn't be available as default option

 Now you can start your apps with jquery with rails new myapp -j jquery, the default is still prototype
