This is a fairly big rewrite/change for the ruby notifier.

Its not complete but I wanted to deprecate lots of old interfaces for the ruby notifier.

Changes

-config.ignore_classes now no longer accepts strings

• Bugsnag.notify_or_ignore removed - now call notify directly
• Bugsnag.auto_notify removed - now call notify directly
• config.delay_with_resque removed
• Bugsnag::Notification now Bugsnag::Report
• notify now only supports the block, you can no longer send in overrides hash
• config.use_ssl removed, now set protocol in config.endpoint
• config.vendor_paths removed (Should we leave this in for people that locally install gemfile?)
• after_notify_callbacks removed
• Capistrano support removed - will go into a dedicated gem
• Deploy support removed, will go in the capistrano gem
• params_filters renamed to meta_data_filters to be clearer
• config.debug removed and instead use the logger directly

Probably more besides. This cannot be merged until the capistrano gem exists.
