[shared] rails exception logger

https://github.com/defunkt/exception_logger

installation:
- ruby script/generate exception_migration
- rake db:migrate
- in application_controller.rb add

include ExceptionLoggable
rescue_from Exception, :with => :exception_handler

private

def exception_handler exception
log_exception exception
render "/500.html"
end

the default controller and view using prototype.js instead of jquery so i created my own controller view under admin namespace. the database pretty simple and similar to rails exception notification
