[Elecraft] P3 Utility enhancement

[Mike Reublin]

I'm using V1.13.2.3 on my Mac. It would be very handy to be able to type a changes into the Local folder box and have the utility create it. The box allows editing, but changes back to what was there before. 

Currently it's populated with "Macintosh HD:Users:Miker:Library:Application Support:Elecraft:P3 Firmware:MCU_1.25:". I'd like to be able to change that to ""Macintosh HD:Users:Miker:Library:Application Support:Elecraft:P3 Firmware:MCU_1.26:" and have the new folder created.

I think I recall the Win vers of the K3 util does that.
