Added user_info data to notices, to retrieve and display info about the currently logged in user.

This allows us to know who took the action that caused
the error, so we can follow up via email or phone
if we need further information about the context.
Only show Application User tab if present
Renamed user_info => user_attributes
Added rails_autolink gem
Fixed User Attributes partials
Pegged json to 1.4.6 (getting strange errors: symbol lookup error: /home/vagrant/.rvm/gems/ruby-1.9.3-p194/gems/json-1.7.1/lib/json/ext/parser.so: undefined symbol: capi_get_constant)
Fixed user_attributes condition when no @notice
Fixed ruby-debug conditional in Gemfile
Improved error matching by removing fragments from methods (e.g. erb fragment hashes). Also use first 3 lines of backtrace for fingerprint.
Added section to README about using airbrake_user_attributes gem to provide user information in error reports
