Model implementations only work with a single database

[GoogleCodeExporter]

Because the classes in the Model inheritance chain (mainly for
vanilla/dbmodels/3) are used statically and define a lot of static class
members, the ORM can only be used with one database/database connection.

Not sure if this is worth doing anything about, or how it might be fixed
and still retain the static invocation of model methods.

See comments on r290.
