Weigh Display Fields

Issue Summary

Right now, there is no way to weigh or sort the profile fields displayed in the role contact form. You can weigh the fields inside the profile module but you cannot weigh the categories within profile module (that I have found - it just lists them alphabetically).

I would like to see a column added to the "display fields" tab of the Role Contact Module that would allow me to weigh the order of the fields listed.

A related request would be to have the Role Contact module to also use (as an option) the categories defined within the Profile module. This is secondary to me, however.

Thanks!
