Update Real Name to 7.x-1.2

A patch to update Real Name to 7.x-1.2.

The latest version of Real Name introduces a hook_requirements() check that verifies that all user registration emails have had their default user name tokens replaced with their raw equivalents since the default tokens display realnames which cannot be used for logging in or resetting passwords (which leads to confusion).

In addition to incrementing the module's version number the patch also featurizes the emails that require their tokens to be replaced and a strongarm alter is added to switch between the default and raw token messages depending on whether the Real Name module is installed. hook_modules_enabled()/hook_modules_disabled() are also implemented to revert the features when Real Name is enabled/disabled.

Tested #1 with an existing Commons install and verified that user realnames continued to function properly. Also verified that the user registration emails had their tokens replaced correctly and that all of the Real Name requirements were met.

Committed #1 to Commons 7.x-3.x.
