Fix a number of errors in the config.gem mechanism.

* Rails::GemDependency was missing definitions for hash and eql?, causing Array#uniq to not work.

* If several versions of a gem are unpacked in vendor, now chooses the highest if no version is specified.

* streamlined add_load_path. Now sets up Rubygems correctly to allow 'gem' to find frozen gems, with
  gems frozen to vendor/gems and specifications in vendor/gems/<gem-name>/.specification

* Rails::GemDependency#specification would return a spec for the highest installed version, even for
  frozen gems and/or previously loaded lower versions. See in part ticket #1123.

* removed vendor from default_load_paths - it was causing autoloading to append Gems::Gems::<gem-dir> to
  constant names

* added additional tests for loading frozen gems.

* incorporates the fix from #1107 for vendor rails

* defers to freeze:gems for handling the Rails framework. gems:unpack WILL NOT place a copy of Rails
  in vendor/gems. Should close #1123 completely.

* incorporates, via using the gem loader for frozen gems, fixes corresponding to #227, #324, #362, #527, and #742.

* gem plugins now work the same whether frozen or not. Correctness of the behavior is a matter for another ticket...
