Change "my_additional_field" to "sharethis" or similar

In sharethis.module on line 320, it says:
$node->content['my_additional_field'] = array(

It would be so much nicer if it used a non-generic name so that those of us editing tpls know what we're referring to. Like so:
$node->content['sharethis_widget'] = array(

Not a huge deal, obviously, just a nice-to-have.

This module has made my sharing life so much easier, thanks for getting it up and running!!
