Use bash for submission

[nsheff]

Awhile ago I ran into an issue using looper in an environment that wasn't running on bash.

This solved the problem. I'm not sure this is what we should do, but wanted to document that if the shell isn't bash, then the config files can't use bash constructs... so we may want to think of a systematic way to handle this.

• wait for divvy 0.7.0 (which chmod +x the written script)

Is this PR still relevant?

[nsheff]

Yes, see refgenie/refgenomes.databio.org#4

so it comes up occasionally. I think I never found a really satisfying answer to it...
