Morpho

this is a continuation of bug 669. Only the relevant, incomplete items from 669
are included here.

1) Collect contact information about the user in the profile. When they type
their last name in a eml-party surname field, pop up a window asking if they
want to use their own info, and fill it in for them if they say yes.

2) When someone enters a surname in, look it up in ldap, either on each
keystroke, or when they move to the next field. This may be something we want
to ask metacat to do. Pop up a dialog that doesn't prevent them from continuing
to enter the name, and ask if they want to use one of the ldap entries. If they
say yes, format the entry in EML and fill in the values for them.
