#19 User-defined fields as picklists

[Dan Abushanab]

For the four new 'custom' fields added to the mod -
would like these to be configurable to choose from a pre-
defined set of choices, instead of having them free
form.

As free form fields I can't use them reliably with people
self-editing. But if I could make them picklists I could
use them then.

Also - might be nice to have the option to 'hide' the
fields if they're not in use, just to make the UI a little
cleaner for non techie users.

What I think I'll do is hide the fields if the labels aren't
changed from the defaults. That will go into this next release.

Changing field types will have to borrow on the technology I
crammed into phpwsListings, and will have to wait.

Alright custom fields are now hidden if the labels are
empty. New installs will default the fields to empty as
well instead of "Custom 1" etc.
