Metacat

Got rid of some debugging.

Modified the lsid code to lookup document type-appropriate stylesheets from
the lsid prooperties file.

Reformatted LSID code for consistency.

Added apache commons logging to the LSID servlet using log4j. Remove println statements.

Removed extra package declaration in LSID java file.

Initial checkin of LSID support code for metacat. The LSID support here
provides access to metacat documents through an LSID identifier. The
identifier takes the form:
urn:lsid:ecoinformatics.org:jones:1:1

See http://lsid.sourceforge.net for more details....
