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).

Improvements to the OBFS stylesheet, especially for EML display. Now we
import the eml_xsl.css stylesheet and override several of its templates.

took out h2 tags, added valign=top to TD containing logo, and added missing quotes on a link target=top

Enabled stylesheet parameters to be passed through metacat even when the
'query' function is called. Previously, query would interpret all
parameters except a few hardcoded ones to be pathexpressions that should be
built into a squery. Now, metacat.properties contains a new configuration...

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.

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)....
