Metacat

Removed all DTDs from the metacat module in anticipation of getting
them from the standard "mdstandards/eml" module. This will mean
that an update to the build script is necessary in order to copy and rename
the dtds from the eml module.

default css stylesheet so that metacat will look right

added input box in replMain web page for downloading of the certificate file
from the specified URL of the source server
added new metacat property "certPath" for uploading the certificate file onto destination server

Minor bug fixes following change in style handling. Fixed image locations,

More fully completed the eml-dataset XSLT stylesheet for translating
into HTML format. Now more of the relevant fields are completed, and

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 index page to launch proper initial query.

Updated stylesheet to reflect the new eml2 schema.

Revised build.xml and metacat.properties to make it easier to
install alternative stylesheets for metacat. In the process,
replaced the deprecated copydir and copyfile commands in build.xml
with appropriate "copy" commands.
