Metacat

CHanged style-set handling for case when a stylesheet for a specific
doctype has not been registered. Now we are using a simple "ascii tree"
view of the XML document. I'm hoping we can get a nicer generic display
set up over the long run, but for now this handles the basics.

default css stylesheet so that metacat will look right

Minor bug fixes following change in style handling. Fixed image locations,
cleaned up main resultset stylesheet.

More fully completed the eml-dataset XSLT stylesheet for translating
into HTML format. Now more of the relevant fields are completed, and
the coverages are shown. Still need to systematically address every
field that could be present, but I hit the major ones.

Modified metacat stylesheets to now use a "style-path" filter for setting
the path to XSL and CSS style sheets. this allows the style
location to be configured independently of the main web url for metacat
links.

Updated stylesheet to reflect the new eml2 schema.

Fixed returndoctype param.

Updated stylesheet to use new package returndoc type for searches
(eml-dataset-2.0).

specified the correct param list about the "read" action changes

chaged the hidden input box from "relation" to "docid"
