Updated DROP script that was missing tables and sequences.
New SQL tables and db upgrade scripts that define a new table stucture for identifiers and delete the previously unused accession_number table. This is in anticipation of supporting LSID identifiers. Currently these tables are unused by the servlet but are in place for discussion.
Refactored the build to use a <path> element for the classpath ratherthan ant properties. This makes the classpath easier to manage, but requiredchanges throughout the build. I think everything should still build fine --it works for me.
Upgraded the JDBC driver for postgres to the version 8 driver....
dropping the sequences as well in the postgres drop list.
Added new tables from metacat 1.5 to the drop list.
New schema changes, including upgrade scripts. Includes renamed postgresscripts.
