[MOV] link_tracker, various: more link shortening tools to mail.render.mixin

PURPOSE

Move links shortening tools on mail.render.mixin to have rendering and
post procesing tools available on that mixin.

SPECIFICATIONS

Move html and text links shortening methods on mail.render.mixin class.
That way rendering and post processing is done in that mixin instead of
being specific to link.tracker model. Indeed those methods are tools and
not really business related methods.

Future commits will improve the way mail and sms composer use the render
mixin. This commit is therefore both a cleaning and preparing commit.
