Metacat

Persist skin properties across installations

Change MetaCatVersion to MetacatVersion

Create database and shared directories for database management code and shared code respectively.

Implement stop method in services. Stop all services when shutting down metacat. This primarily keeps scheduler from hanging with open threads.

Added generic scheduler and workflow scheduling functionality.

Add archival read funtionality (jar/kar/war files)

Roll back replication user changes. Fix code that converts access levels to integer and to text.

Introduce replication user. Use the fileutil writer methods instead of writing directly.

Beef up exception handling from file utilities. Move UtilException to MetacatUtilException to eliminate conflict with similar exception in utility package.

Separate the concept of a backup file location and a metacat external directory location. These can be totally different.
