Metacat

Updated MetaCatServlet so that it supports a web-based interface for configuring its own properties the first time it is run (determined by the property "configured" being set to false). Which properties are exposed in the web interface is determined by the list of properties in the 'metacat.properties.metadata' file. This file is managed by the new OptionsMetadata class in the utilities module, and provides information that allows metacat to build a human-readable configuration page for the properties. Still need to finish filling out the information in metacat.properties.metadata for the rest of the properties that we want to be editable. This autoconfiguration process is the first step towards building a turnkey installer for metacat....

Initial import of interactive map components for the following skins: esa, knb2, knp, obfs, nceas, nrs

restored original styles to knp-specific layers

I'm adding a set of EML XSL stylesheets that are separate but similar to those
found in the lib/style/common directory. I have created a directory called
'shared' (in libstyle) and put these modified stylesheets within it in order
to maintain backward compatibility with skins that were written previously...

I'm adding the two html templates from the OBFS skin developed by Matt Jones.
These were used as reference files in the PISCO skin.

I'm adding the two jsp files that originated in the KNB skin developed
by Matthew Brooke, modified for the PISCO skin.

I'm adding the PISCO-specific XSL stylesheets used to transform EML documents to PISCO web pages. Notice that resultset.xsl is now in this templates directory, rather than in lib/style/common since it has PISCO-specific styling.

I'm adding in a number of supporting image files that make up the PISCO header, navigation bar, and footer sections of the styled web pages.

I'm adding the legacy PISCO skin to metacat as a starting point to doing CSS-based XSL styling of XML documents in the data catalog. These files were based off of the OBFS and KNB skins.

Removed the hadcoded servlet context and instead get it from the HTTP request to allow the config files to be installed in any context.
