Add "Board" as a profile field for OSF staff

[Paul Everitt]

Let's say we also have a field on the <user>:

<user> <board>Early Childhood Advisory Board</board>

Getting that value displayed on the actual profile...I can't remember
the state of the art on customizing profile fields per KARL instance
(OSF, Oxfam, etc.). I think though that it should be a matter of
configuration, not coding.

Thankfully we don't have to drive that profile field from the <category id="boards"> values. For example, we don't do that for <category id="departments">. Instead, OSF joins all those into <departments> directly on the <user>

<user>
<departments>A, B, C</departments>

They'll do the same for a <boards> field. We just need to get <boards> into the display.

This field is now present in the profile, but is not being populated by GSA sync (there is no '<board>...</board>' element which rolls up the categories as '<department>...</department>' does. It is not editable by non-admin staff.
