Remove Package from .Info file

This module is not part of a package, therefore the package = Registration is incorrect. See Writing .info files (Drupal 6.x):

In general, this field should only be used by large multi-module packages, or by modules meant to extend these packages, such as CCK, Views, E-Commerce, Organic Groups and the like. All other modules should leave this blank. As a guideline, four or more modules that depend on each other (or all on a single module) make a good candidate for a package. Fewer probably do not.
