Improve iOS simulator selection

[iRonin]

PoC WIP

Running titanium build --platform iphone with ti config ios.autoSelectDevice false gives user the prompt to select iOS simulator out of all available, eg.

Which simulator do you want to launch your app in?
8.1
   1)  iPhone 4s
   2)  iPhone 5
   3)  iPhone 5s
   4)  iPhone 6 Plus
   5)  iPhone 6
   6)  iPad 2
   7)  iPad Retina
   8)  iPad Air
   9)  Resizable iPhone
  10)  Resizable iPad
Select an simulator by number or name [1]:

Is this something we could merge into this plugin?

Note: This is 90% of Python code I've ever written. I left print()s and commented out code for reviewer to test it easily. I'm also not sure how the flow with selecting sim version and SDK version should work (I have only single SDK installed).
