Support multiple elm apps (mains)

[not-my-profile]

Let's say you have a file Foo.elm with:

module Foo exposing (main)
import Html exposing (..)
main =
  div [] [ text "Hello from Foo!" ]

and a second file Bar.elm with:

module Bar exposing (main)
import Html exposing (..)
main =
  div [] [ text "Hello from Bar!" ]

elm make let's you compile both apps to a single output file:

% elm make Foo.elm Bar.elm --output out.js          
Success! Compiled 2 modules.

    Foo ───┬──> out.js
    Bar ───┘

Unfortunately this apparently doesn't work with elm-live as it requires a single main.
