[patch - MapTool] Key map NPE Fix

[Lee]

Discussed here, this fixes the unexpected input map behavior experienced under Java 7. Apparently, clearing the menu bar of it's mapping scheme results on bad calls downstream when a user hits a key on the keyboard.

I suspect that Java 7 handles the instantiating of Swing components differently, prioritizing the menu bar creation, wherein the map wipe that happens further down the launch process corrupts its input scheme. This is all conjecture, of course. While I could dig deeper into this, this patch seems to fix things, so I think I could be of more help elsewhere

Edit: put in a more accurate link of the reported bug

Heh, commenting out one line fixes it. I love the simple ones (once they've been found, that is!).

Good work, Lee! And thanks for tracking this down! (SVN rev 5943)
