* Slightly revamped basic card icons
All icon classes which were just static text have been removed, and instead replaced with a static instance.
A new icon for reach has been added
Some icons have been reused for new abilities (hexproof for shroud and ward, infect for toxic)
When a card would have two icons of the same type, the icons are instead combines into one with a combined hover tooltip.
* Fixed missing capitalization on ward, hexproof
