Changed default binding for "foreman start"

Development
#1

Hey all,
Up until today, "foreman start" command bind both rails and webpack to
0.0.0.0. This has changed since [1] which was merged this morning.
Currently "foreman start" will bind to localhost by default. Should you
want to change that you can either:

  1. Run "BIND=0.0.0.0 foreman start"
    or
  2. Create a ".env" file which is read by foreman (the other foreman :wink: )
    and add to it "BIND=0.0.0.0".
    By the way you can add other environment variables to .env
