Rename "Uncategorized" to "Other"

Pursuant to the discussion on the devel list here: http://lists.drupal.org/pipermail/development/2006-November/021069.html it looks like we need to do this quickly before this gets spiralling out of hand.

The gist is:

- The "package = " entry in .info files should be restricted to modules which are actually part of a package. For example, "Views Bonus Pack" module is useless without "Views" module, thus is part of the Views package.
- "Uncategorized" makes it sound like the maintainer was too lazy to categorize their module, and therefore module maintainers are going bonkers making up every package name under the sun, when in actual fact very few modules should actually have packages.
- The package attribute should specifically not be for categorization, both because categories are in many cases a many-to-many relationship, which is not desirable nor even feasible, and also because people really tend to suck at categorizing things.

I have almost marked this "critical" because this is already getting out of hand and there hasn't been a release yet. But at the very least it's very high priority and needs to get sorted.
