added toString override

reimplemented getImageAsset to use ClasspathImage, instead of an anonymous implementation of ImageAsset
reduced the height of the textbox to leave room for the power/toughness box
fixed casing of activated ability description to match Wizard's conventions
allowed explicit wrapOffset on construction of RenderCtx, instead of requiring it match the font size
