Metacat

Removed unneeded Net::LDAP dependency. Now all authentication occurs
indirectly through Metacat.

Added skin for the UCNRS data registry based on earlier work. Minor
modifications to the templates to accomodate this. Fixed a validation
bug in the register-dataset.cgi, and removed an unnecessary Net::LDAP
login as well because the authentication is handled by metacat.

Fixed validation check for samplingDescription.

Changes to re-enable the nceas admindb access for the production install.

Removed some debugging test code that isn't needed.

Added studyExtent and samplingDescription fields to the registry to accomodate
Sandy's request for a temporalDescription field. This is a little more than
she wanted, but it was needed to satisfy EML minimum requirements.

Added taxonomic coverage and authority fields, and fixed a bug in reentry
with the methods fields. Now we are collecting information on all of the
additional fields Sandy requested except for a general temporal description,
which doesn't fit neatly in EML. Will need to consider how to accomodate...

Added the ability to describe taxonomicCoverage to the registry. This
allows an arbitrary number of species or other taxa to be listed, and the
editing form can dynamically grow through a simple javascript approach
(also used in Methods). Need to test thoroughly, and need to test on...

Added geographic description to the fields of data collected, as it is
a required field and was being improperly defaulted to an empty string in the
XML document. This is a new field for all registries.

Modifications to add "Methods" collection to the data registry, and to
make the forms HTML 4.0.1 valid (in an attempt to figure out some of
the rendering and layout oddities I'm seeing).
