Fix Fastlane

[chelseatroy]

When it's time to deploy this app, it is always a pain. I run into issues with the solutions in the README, and I end up using the manual deployment guidelines for Android and iOS separately, plus a lot of Googling and debugging. To that end, we schedule a week for every mobile release. I'd like it to take a day, tops.

Fastlane is supposed to deploy both platforms with one command, which would be very helpful to achieving this goal. We have a script called buildiOSAndAndroid.sh that's supposed to take care of everything.

I assume it worked at some point. It definitely does not work now.

I don't know what it would take to fix it, and I cannot prioritize finding out at the moment, but having this fixed would make it easier for me tor one of my colleagues to deploy this app.
