Fixed Sqlite3 test again. Inserts were not using squallsql and len() was omitted from an assert.
Dynamic associations of Sql() objects in squallsql implemented -- requires implementer to
link an Sql Class to an SqlAdapter() class variable so it gets associated during instantiation
of the driver. Documentation bug is here: https://github.com/NucleaPeon/squall/issues/16
This function won't be noticeable by the user, but is critical for implementing all db's.
