[racket-dev] The `meta/contrib' Collect

In a recent email, Eli mentioned that the `meta' collect was not meant
for distribution.

However, `meta/contrib' contains scripts that are of general interest,
and IMO should be distributed. For example, we've had users trying to
find the bash completion script, only to realize that it wasn't in the
default distribution.

I propose moving `meta/contrib' to the `contrib' collect, and
distributing it in the default distribution (maybe even in Racket
Textual).
