Allow setting of Procfile via -f or --procfile

Usage:

toreman -f Procfile.test

Thanks for making this first move to make toreman closer to foreman feature-wise!

I must admit I've made a huge design mistake by giving in and letting to accept the layout as the first command-line argument (select-layout ${1:-tiled}). Foreman accepts a process name as the first argument, and by using it otherwise we're breaking this already subtle compatibility altogether.
Accepting command-line options prevents any further extensibility attempts without breaking the one-liner approach.
What do you think of using environment variables instead of passing options?

To meet the design goal of keeping this script one-line'ish, to keep the ability to set the layout, and to be able to choose the procfile to be used would you agree to do the following:

• use the PROCFILE environment variable, and default to Procfile
• remove the usage of $1 for setting the layout
• use LAYOUT environment variable for setting the layout, and default to tiled
• update the README to reflect those changes
• introduce a CHANGELOG.adoc to tell about those changes and mentioning yourself there

I haven't thought of versioning before, and as since this is a breaking change, we would have to change the major version or keep pretending that we were at 0.9 before, and 1.0 now.

Would you like to make such changes?

Oh that's fine too! Never bothered to change the tiling. Will the command look like this?

PROCFILE=Procfile.dev.remote toreman

Never bothered to change the tiling.

Me neither 😆

Will the command look like this? PROCFILE=Procfile.dev.remote toreman

Exactly, that was the idea. Does it fit your needs?
