* 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
