Option to set default profile or default settings per language

For some reason script/Atom.io selects an old PHP 5.5 which is nowhere in my path. So I have to run using a profile which is super inconvenient (extra key comb + select profile + hit enter).

Alternatively add cmd path settings.

(Wondering how command is executed, what is the env/context? I'd say that `/bin/env $cmd` should give the "correct" version in most cases?)
