Basic: remove all error handling override for any class vars to avoid
exploiting private/public/protected settings

Basic: Add MIME lookup table with array. So you can return a File name
description (human understandable) to a mime handler.
See mimeInitApps for basic list

IO: Bug fix for counting prepared statment place holders. If there are
$1, $1, $2 then those are TWO and not THREE

IO: various wrappers for returning PK, Extended return set, Number for
rows
Those will be extended to all variables
