DB_Status

Removed the "sp_version" and "def_data_version" fields.

Renamed the "update_history" field to "upgrade_history", changed its type from notes to string2000, change its Nulls? setting to N (not nullable), and changed the description to "List of MES database upgrades since the first MES installation, including the initial installation; entries, including the last one, are terminated by a semicolon (;) and a space".

After the "upgrade_history" field, added the new field "hotfix_history" (string2000, nullable), with the description "List of hotfixes applied on the current version of the database; entries, including the last one, are terminated by a semicolon (;) and a space".
