Add additional ability icons (#10549)

* 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
