Issue #14 path in role.rb is wrong - change code

* removed invalid alternative pathj to roles.yml in
app/models/cms/fortress/role.rb and added exception
handling, if the file is not found.
* add error message css
* add Exception folder ibn models with exception
MissingRoleCconfigurationFile
Added further translations

I am not 100% sure with the changes in application_helper.rb. If
a developer forgets to add translations for all new roles
in roles.yml, it will trow an error. mybe this has to be done
better.
TinyMCE improvements

* added also the table plugin to tinymce because one will use it eventually
* added the tinymce-rails-langs gem to the Gemfile

Added the possibility to create settings

I think it's a good idea to have the possibility,
to change the title and the name of the CMS via a
configuration file. Therefor I created the class Settings
and a configuration file in config/cms/fortress/global_settings.yml.

Furthermore, I moved the Error class into a Cms::Fortress namespace.
I changed the raise and rescue code to the new Error class
