Mudlet dev exits dialog

I hope I am correct in thinking that Chris7:mudletDev is a current development tip.  Here is my exit GUI that considerably improves on the current mainline offering; where the "Lock" buttons to prevent the exit being used for route-finding for each exit ALSO disabled the exit room ID QTextEdit for editing. 8-P  I note that Vladim when he perused a previous version of this code suggested replacing the four radio buttons for door type on each exit by a drop-down selector with the four options - but this would make the functionality for the same feature for the special exits different (unless I can figure out how to insert the same drop-down as a column entry in the special exits' table widget...)

At present there is no display of doors on custom lines used for normal or special exits (or the 2D mapper representation of non-XY-plane exits: in, out, up and down - the code here supports such functionality though some tool tips will need update when/if this gets implemented.
