split most of the code from config into utils, encode now uses utils as a lib

# Don't be intimidated by the massive size of this file. It provides both the
# raw character decisions made about the encoding scheme as variables, and
# a bunch of tables and functions to make dealing with mana costs and unary
# numbers easier. For the most part the functions should adapt if you change
# the specific delimiters and markers used.
# The decoding from mtgjson format is dependent on the specific structure of
# the internally used mana symbol strings, so if you want to change that you'll
# also have to change the json decoding functions.
# Utilities for handling unicode, unary numbers, mana costs, and special symbols.
