Map Editor crashes when setting sound for Prog. Speaker

[dryerlint]

The entire game crashes to desktop, and it is reproducible.

1) Open Map Editor, make new map
2) Using Entities Menu, place a Constant Combinator and Programmable Speaker
3) Wire them together, either green or red wire
4) Go back to Entities Menu
5) Clear the cursor using "Q"
6) Click on the Speaker
7) Deselect the "signal value is pitch" button
8) Open the "sounds" dropdown (the one that has things like "damage-alert" or "achievement-unlocked")
9) Click on any of the sounds
10) Game crash

It is a minor bug, but it does seem to prevent use of the Speaker when making maps, so it is probably worth fixing

Thanks for the report. Fixed for the next version of 0.15.
