More clear and explicit versions handling is necessary

[kirillt]

Hello, I think elm-desktop-app should:

1. not allow project initialization with wrong version;
2. have documentation about supported versions.

$ uname -a
Darwin fritz.box 17.5.0 Darwin Kernel Version 17.5.0: Mon Mar  5 22:24:32 PST 2018; root:xnu-4570.51.1~1/RELEASE_X86_64 x86_64
$ elm --version
0.19.1
$ elm-desktop-app init
...
Success!
$ elm-desktop-app run
...
data['elm-version'] should be equal to one of the allowed values

I'm getting this error --- is there a workaround?

What are the allowed values? I also have 0.19.1, and I get this same error. I downgraded to 0.19.0 based on my search results of the project for elm-version, but I still get the same error.

I am getting the same error in elm 0.19.1. Are there anz plans to make this version compatible?
