Need to use variable to reference home directory rather than hardcoding it

[conradlee]

Hey Andrew, I was just playing around with this and noticed an issue with a line you likely added recently:

https://github.com/amontalenti/home/blob/98bf1e9513468fc690fd0d5d711232fc67908858/.bash_env#L106

[conradlee]

Oh wait a minute--is this repo actually supposed to be usable by other people? Searching for "/home/am/" in this repo reveals lots of places where you've hardcoded your home directory. Maybe this is just meant for your reference and to allow others to lean over your shoulder a bit (rather than as a project that others can clone and use out of the box).
