Dismissing a Hero - Update

Due to the scroll - ash update today, the check list for dismissing a hero needs to be updated. Thanks to pectrox for reminding me.

1. Remove ALL items from the hero.
2. Remove ALL troops from the hero.
3. Use ALL arena points that hero has. Exchange them for items, or just exp scrolls.
4. Sell all BoE items bound to the hero.
5. Unequip all scrolls (and get the ashes).
