Next step in upgrading Tracks to Rails 2.2. Some highlights:

* Ran rake rails:update
* Added old actionwebservice framework
* Updated RSpec and RSpec-Rails
* Removed asset_packager plugin (not compatible, Scott no longer maintaining), and replaced with bundle_fu. See the bundle_fu README for more info.
* Hacks to UJS and ARTS plugins, which are no longer supported. Probably should move off both UJS and RJS.
* Hack to flashobject_helper plugin (upgrade to Rails 2.2-compatible version if/when it comes out.)
* Hack to skinny-spec plugin, for Rails 2.2 compatibility. Should check for official release.
* Hacks to resource_feeder plugin, for Rails 2.2 compatibility. Should check for official release (not likely) or move off it.
* Addressed some deprecation warnings. More to come.
* My mobile mime type hackery is no longer necessary with new Rails features. Yay!
* Updated environment.rb.tmpl with changes

TODO:
* Restore view specs marked pending
* Fix failing integration tests.
* Try selenium tests.
* Investigate OpenID support.
* Address deprecation warnings.
* Consider moving parts of environment.rb to initializers
* Address annoying config.gem warning about highline gem
