Removed getuser and getuserbyid from arylib in favor of db alternatives; added semicolons to various 'use strict's
Reorganized test comments; Added flash dep and req
using db findhelpers instead of arylib in auth; fixed login flash; fixed job session check; fixed passport auth strat;
fixed findUserById by using ObjectID object; redid auth/session logic; wrote findUserByID test

findUserById was just using a raw id string instead of a New ObjectID(id) object and now is working correctly.
Auth/session logic is working: using arylib authenticate instead of rewriting it in localstrategy;
session serialization logic is saving our id as req.session.passport.user instead of ._id; Can't figure out how to change it so I changed everything else to match;
wrote a findUserByID test;
