Title: Exception: Unsupported filter type (tinyint)

Tinyint is one of the possibilities when sqlalchemy reflects an existing table. In mysql, it's used in place of the boolean type. When flask-admin tries to apply a filter to it, it throws the unsupported filter type error.

I tried this and the boolean converter seems to work just fine on tinyints.
