great!

@linnchord hi, I just fixed a regex bug.

@lepture that emoji_list should be a set for faster lookups. ("if name not in emoji_list")

@lepture, I'd really like to turn this into a pypi installable- is this on the cards for you? Totally up to doing the legwork and maintaining the project / package.
