Bash module

I'm an idiot and forgot how pull requests work so this is just a continuation of https://github.com/mutantmonkey/phenny/pull/75

This module saves 100 lines of backlog at any time, then allows people to grab quotes by doing:

<a> hello
<b> yo
<c> ayy lmao            --start quote here
<b> lol                        --end here
<a> .bash c 1 b 1

and saves each quote to a plaintext file in ~/.phenny/bash_logs
