[2020] Manually Destroying a skill object no longer halves the CD (or remaining charges)

Pretty big change to this particular mechanic. Before, if you destroyed a skill object, it would put you at half the max cooldown. For skill objects with charges like the Hive, it would put it at half the current charges at time of manual-destroy.

Now after TU8 update, you incur a max cooldown, and charge-based things have their charges completely emptied.
