[chirp_users] CHIRP 0.1.9b12

Hi all,

I just posted 0.1.9b12 with a couple of changes:

- Add call channels for ic9x - Show a file type on file->save as to make it a little more clear that you can't change the file type just by saving

On my ic9x, CHIRP is incorrectly showing a TONE setting on one of my call channels, but not the other. I've looked at the memory data and it sure enough has the bits set indicating the tone encoder, even though it does not display on my radio's screen. This seems relatively minor though.

So, hopefully this looks good enough to call it 0.1.9 final. Dave, any objections (after you test this)?

Thanks!
