This fixes mailgun#206. Before this change, when multiple Python processes are simultaneously doing a `from flanker.addresslib import address`, it's possible for some of them to crash in `ply` code. See dabeaz/ply#184, where I attempted to work around this issue by changing ply. You can see in this comment: dabeaz/ply#184 (comment) that the author of ply suggests two workarounds for this issue: 1. Remove `ply` as a dependency in setup.py and copy the source code of `ply` into `flanker`. 2. Disable writing parsetab files to disk when invoking `yacc`. 2) seemed like the simpler solution to me, so that's what I've done here.
