lint shebang executable path resolution (any scripting language)

[mcandre]

No other linter appears to do this, resulting in a proliferation of Works On My Machine busted scripts from devs who don't know better.

funk:

• Encourage #!/bin/<interpreter> for shell languages (POSIXy and non-POSIXY).
• Encourage #!/usr/bin/env <interpreter> [options] for non-shell scripting languages (Ruby, Python, etc.)
