Metacat

Modifications that allow working group entries to be put in as creators, and
a whole bunch of re-formatting for horribly formatted code that I need to
read to finish this thing up.

Updated registry further for NCEAS-specific needs. Confirm data template
now handles new wg field. Still need to write WG metadata into EML document.

Additional work on the NCEAS/AdminDB integration. Working Groups now
presented as a dropdown box for multiple selection. Need to write the
info to the XML file now and handle it in confirmation template.

Preliminary changes to support the NCEAS data registry connection to the
AdminDB to retrieve project lists.

Updates that allow registry script to update the lastid field more efficiently
by calling the metacat 'getlastdocid' function for a given scope. Also some
debugging support added, and a bug where the error message was inproperly
saved across calls to metacat, resulting in spurious error messages.

Remove email notification from registry script.

This is the merge from the branch WEB_UI_REDESIGN_BRANCH back into the head.
The only files that have been removed are those in lib/style/eml2; other files
that have been cvs removed (only from lib/ and lib/style) have been re-added
elsewhere (i.e. moved from one directory to another)....
