Metacat

Added new stylesheets for displaying the eml-attribute and eml-entity modules.

Changed the link urls in the eml-dataset display stylesheet to use the
default style-set as set in the build file rather than hard-coding the
value 'html'. This allows more flexibility in switching styles, for example
when setting up the marine, nrs, and obfs sites.

updated all of the returndoctypes so that emlbeta4 and emlbeta6 will show up in the resultset.

fixed a couple bugs with doctypes that I found while setting up a demo

Updated documentation to reflect new installprocess.

Modified build.xml to properly copy the docs into the distribution, which
required some changes in the ant token filtering scheme.

added new docid to returndoc for web form

New version of the IE5 stylesheet that is XSLT 1.0 compliant.

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.
