- Improved detailed spell ability descriptions when paying costs/targeting by getting rid of the Targeting ERROR text in the prompt box at the time when the SA is not yet targeted by the player.

- Made the detailed SA descriptions on paying costs/targeting optional (can be enabled/disabled in preferences, enabled by default) for people wanting the old behavior (which might especially be useful for mobile Forge on small screens).
