New HP41 Emulator for OS X

[anetzer]

Thank you for this beautiful emulator.

I'd prefer a slimmer frame, as my screen is often crowded. But skins are for later, I suppose.

I had some immediate crashes on my MacBook Pro. I could send details via PM, if this continues?

On another machine, the emulator is more stable.

First thing I noticed: USER-indicator stays lit, when I turn off the emulator via its ON-key.
