Fix decode_www_form to work with ruby 2.1
Add possibility to overwrite last_updated_at date
This partially solves problem of too many translation when moving from staging to production and synchronizing translation keys between environments.
Bootstrap3 changes / fixes.
Source's last_updated_at will be set now to now() by default.
There is possibility to change that behaviour via module settings in app initializer
