Import problems with MoveableType and MySQL 5

[bungeman]

import/mt.php does not work with MySQL 5 out of the box since it produces bogus INSERTS. One can get around this by using a quick and dirty plugin which turns off strict mode in MySQL, but its really hard to figure out this is the problem, and besides, its bad form to have invalid SQL querries.
