Added a big old construct-based pkm parser. #183

# encoding: utf8
u"""Defines a construct `pokemon_struct`, containing the structure of a single
Pokémon saved within a game -- often seen as a .pkm file. This is the same
format sent back and forth over the GTS.

# TODO:
# - strings should be validated, going both in and out
# - strings need to pad themselves when being re-encoded
# - strings sometimes need specific padding christ
# - date_met is not optional
# - some way to be more lenient with junk data, or at least
# - higher-level validation; see XXXes below
# - personality indirectly influences IVs due to PRNG use
# The entire gen 4 character table:
