implemented getAlliedColors
implemented the core of the text-parsing stuff
added toString for the text and break implementations
created simple Artwork implementation
created a <br> element in the schema for putting explicit line breaks into text, and changed both flavor and reminder bodies to accept it (rather than being simple strings)
changed isMultiColor to not subtract COLORLESS, as if it's in the colors array (which it never should be), it should count.
finished implementing the importer
