1. Fixed a bug in the oracle version of acs-mail-nt-create.sql
2. Fixed a bug in the oracle version of the APM - a standard SQL92 left join was being executed rather than the nasty Oracle-specific notation.
3. Futzed with the APM a bit - you can now only set "watch" commands on those .xql files which are used by the current installation, you can only install packages supported by the current installation's RDBMS.
1. Added a check that PG was initdb's with the collation order for characters that we expect.
2. Jon added a "sql/common" directory for the insert statements which load data for acs-references, so I added a new datamodel type "common" to the APM.
3. Created a new db API routine that returns true if a given db_type is compatible with the current RDBMS.
4. Added a workaround for a PL/pgSQL "execute" bug in acs-workflow (other cases had been fixed previously by others but this one was missed)
