Major rewrite of interpreting when pear is active

[supertopher]

Catches lack of section before removal get-email returns correct error if it should

this needs a refactor, but proof of concept

closes #60

Cleaned it up. From commit msg:

Removed exit code from get-emails -- can't find a reason why a getter script needs an exit code? it returns a falsey value if the it fails anyway

Lemme know if I'm dumb & totally missing something here.

this looks good. feel free to merge if you are confident but i haven't tested yet. i'll try to get to it today.

Fairly confident. Hope this doesn't come back to bite me in the ass.
