Metacat

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).

New formatting and text for the NCEAS data registry.

Configuration file for NCEAS registry.

Adding style files for the new NCEAS skin for metacat, which includes
files needed for the NCEAS data repository.
