#1111 Support for OUI28/MA-M and OUI36/MA-S

* new oui importer using IEEE csv for MA-L+M+S

* schema update for new vendor table

* change vendor to manufacturer because Device has a vendor field

* remove oui from manuf table, and update node oui after manuf update

* faster way to bulk update node oui

* switch from using oui table to manufacturer table for vendor lookup

* some other oui cleanup

* faster/scalable way to join a macaddr to manuf table

* remove device.oui support

* update node oui in bulk at end of macsuck run

* correct literal sql instead of bind

* more efficient to get oui base for each mac

* comment better the base lookup in macsuck
