Metacat

calculate object size using the size on the file system rather than re-reading as an input stream.
Now only EML document bytes will be read twice: once for the checksum and again for parsing out datapackage details

system metadata generation optionally skips entries that have already been generated (data size, checksum) but allows the latest EML that describes them to have the last word on object format

remove DML for parsing -- the D1 EML parser still uses DOM, so this may not be too big of a perfromance improvement

only attempt to update date-like nodedata values.

include generate system metadata upgrade in the success flag

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.

rollback processing Error change -- creates a loop on error. ugh

report processing errors after exceptions have been caught and recorded, otherwise the web UI is blank and there is no clue what happened unless you look in the logs.

fix a bug in MNodeService.replicate() where the checksum value was being compared to the computed checksum object, not its value.
