[development] File upload and convert

[Kevin Reynen]

@earnie Please stop telling developers discussing development to use the
support list.  This list was started as "a list for Drupal developers"....

http://web.archive.org/web/20110522011442/http://drupal.org/mailing-lists

At some point the description of the list was changed to core development.
Since core conversations rarely happen on this list, I'd like to see that
changed back and limit suggestions to use the support list to questions
about using Drupal or a  specific module.
