Metacat

only attempt to update date-like nodedata values.

more clean up - reuse prepared statement for data update

look up nodedata values first, then update each one - trying to avoid out of memory exception.

close prepared statement only if not null

use logging, not system.out

change upgrade scripts/routines to use 2.0.0 version number instead of 1.10.0

make sure we close the prepared statement always

do not use XML files for storing SystemMetadata - use DB tables only.
