Merge functionality of batchlist and resource table into a single table -- batchlist

[dfcoffin]

Currently, the system keeps the subscription uri value in the "resource" table and assigns "batchlist" as a foreign key. The only element of the "batchlist" table is the key field. The ESPI standard defines the contents of the current "resource" table as being the contents of the "batchlist" entity. Making this merge brings the current implementation into alignment with the ESPI standard.

Since this change impacts the database files, it should be coordinated with the update for bulk processing.
