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).

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)....
