Metacat

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.

Harvester forms to support single file upload to metacat.

made results page table header into <th> so we can apply a different css style to eml stylesheet subheaders. added whitespace above& below section headers

cleaned up css greatly by importing eml css and knb css

knb.css now impots common eml css file - still need to fix layout in eml display tho' - something is being overridden and messes up alignment

changed knb skin index page to forward to knb site and include any user params in url. changed resultset.xsl so qformat is handled properly in posts. changed build file to copy default.css from eml checkout to style/common so other skin-specific css can import it if reqd

added search gif used in default homepage

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)....
