Title: List all the environment variables in Dancer2::Config

List all the ENV variables supported by Dancer2 in a central location.
Most of them are documented elsewhere, but don't mention the ENV var. In
those cases a link to the docs are provided instead of re-documenting
the feature.

One question though: what does DANCER_APPHANDLER do? BTW DANCER_WARNINGS seems to be unused.
