Improve app environments

[levibostian]

I have been doing a lot of thinking and reading up on app environments (development, beta, prod, etc).

I am slowly starting to move away from having app environments and instead having 1 environment where the app behaves exactly the same way in all of them except that some values such as the package name and the API endpoints change.

Why is this?

• Recently, I have started to have issues with Firebase Crashlytics not recording logs or crashes in 1 of my apps. That is because it is setup incorrectly I found out. Well, during development of my app, I have crashlytics off but it's on in beta and prod. I should instead of development have crashlytics installed but just have it point to a different app within Firebase console so that the errors are separated from each version of the app. Therefore, I can test to make sure that crashlytics, and all other features of my app, are always working.
• Improve the readability of my app's code. Rather the thinking, "what is enabled and disabled depending on the app environment?" I can instead concentrate on the app working.

See this issue for more details.

Merging with https://github.com/levibostian/AndroidBlanky/issues/58

After doing these changes on iOSBlanky, just using .env alone is a huge change. Much better.
