BF: Code Type is now set correctly on opening the dialog

Previously, the code type was forced to either Auto->JS, or Both, because
code type selection was conditional based on whether metapensiero was
installed. This fix now unselects Auto->JS if metapensiero is not
installed, but otherwise loads previously selected code type.
