Minor bugfixes

If you don't have an old Voice of the Mummy board game anymore, or if you're out and about and bored, the tvOS game-play version is now available on iOS! You can play a version of the game electronically on your device against competing bot explorers.

It's been a while! No major changes; just making sure this works on the latest iOS versions.

Update for iOS 15 compatibility. Minimum supported version is now iOS 12.

Minimum iOS version supported is now iOS 10 so the app can play sound regardless of the setting on the silent switch. Added a page with the instructions for the board game in case someone has the pieces but not the instructions on how to play.

Small UI tweaks and bug fixes. Added a tvOS option, too!

Update for iOS 11

Fixed a bug that caused captions to not go away after the voice finished playing.
Added an information icon (little "i" in a circle) button to bring up the information/action menu, since long-press isn't very discoverable.
