[SML] RigCalc for iOS and Android is now free (as in gratis)

> I've changed the price in each developer's console- it may take a little while for that to be reflected in each app store.

Free for Android already, just downloaded it.

> Please share with all your friends/students/coworkers who never quite splurged on the $5 purchase, and enjoy!

I hadn't realised it was that cheap, but I may well never actually use
it so free is the most appropriate price for me :)
