Balancing idea: improve action mechanics when grabbing on ring/rope

[Aceearly1993]

Ring/rope mechanics, in the current shape, are designed pretty badly. Players are not allowed to attack when directly grabbing on rings. Also players cannot throw sub weapons while going upwards on ropes. This would cause unneeded/unreasonable difficulty barrier for newcomers at some specific spots in Castle Clockwork.
One main problem is in Vanilla game there's no such animation data for these actions despite slots for these were prepared. So this task will most likely need sprite artists who can deal with them.
