[TriEmbed] Dash FCC info and model corrections

[Pete Soper]

OK, now I'm emulating an American national political convention (take 
your pick) in terms of confusion.

Based on Shane's earlier msg about having model 29 marking on his IoT, I 
asserted it has to be the same as a rev 2 Dash (and I swear the plastic 
in the photo on the AWS web site looks different).

But I'm VERY VERY HAPPY Shane corrected this with the info (with the 
photos in an oversize msg I'm allowing onto the list right now) that the 
IoT uses the rev 1 Dash hardware, because *that is properly 
programmable* hardware. It's going to be straight forward for anybody to 
free their IoT  button from AWS with alternative firmware.

The bad news is that this has the welded on lithium battery and cutting 
the bottom off would be mostly useless.
