removed Card.locale
added Card.setKey next to .setTitle
added RasterImage.url as a property
line-wrapped the long rule- and flavor text blocks
changed creature levels to have an explicit label, rather than start/end.
added accessing allied colors to Card, storage in DefaultCard, exposed it through descriptor, and added alliances to the Dimir Guildcate in the all-in-one-set
fixed the in-body mana symbols for Dimir Guildgate I forgot when I copy and pasted.
set '-' as the psuedo-symbol for COLORLESS
capitalized 'Golem' in the Transguild Courier's subtype
fixed setting cardNumber to dereference the right collection owner
created a 'core' module for housing various core types that are used across different modules and moved the simple color theme, flood, texture and image types there
changed 'size' to be dynamic and lazy instead of deduced on construction (when not provided)
 * created DefaultSymbolGroup
 * added SymbolFactory.getCost which will parse a string of symbols
 * made DefaultSymbol mutable so it can have constructors, but left its fields final
only lands can have allied colors, and levels have ranges, not single levels (so you can describe holes and such)
