type name 32 char limit

I ran into an issue while importing content types into MERCI using merci_import.php. Apparently there is a 32 character limit on the content type name (the machine readable name). What happened is that the names with more than 32 characters were imported into the table for merci_node_type. When I tried to edit them to make them 32 chars or less, rather than replacing these records a duplicate entry was created. Trying to delete the content type only deletes the second duplicate entry.

A solution would be to put a limit on the character length for this variable and not let that value be imported.
