Reduce minimum height of MMapper Editor

[Sebster7]

While I'm building I like to have an MMapper Editor open with my progress, but I want to be able to see the map behind it and the Editor window covers most of it (I have the map on half the screen, and a new map on the other half). I don't need the Editor window so big (tall): less than half the height would be sufficient (actually 3 lines would be sufficient). Right now, I can make the editor window taller, but not smaller beyond a certain point. There also seems to be a minimum width to it set at around 83 characters: that is understandable (as the default width is 80 in MUME) and OK, though I think it could either be reduced to 82, or reduced a lot more and the user would be able to decide how wide to have it...
