[SQLObject] AppVeyor

Hello!

   Kudos to Dr. Neil Muller who implemented test run at AppVeyor (thank
you again, Neil!) I fixed a few minor problems with tests and now we
have Postgres and SQLite tests passing on w32:

   Unfortunately MS SQL tests have a strange timeout.

Oleg.

           Programmers don't die, they just GOSUB without RETURN.
