Fix not being able to place armor on anvil

Placing armor to equip it seems to be a feature when you're in a rush (PvP arena or so).
What do you think about this approach:

• if the pointed node has a on_rightclick callback -> call it
• if the pointed node has no on_rightclick or "Sneak" is pressed -> equip armor

That's a common practice to switch between actions for tools that can also be put into chests directly.

@SmallJoker I didn't think it was necessary to have a check for on_rightclick, but now that I think of it, it makes sense for equipping armor in a confined space where you can't not point at a node.

Works. Will merge in a few days unless there are objections.
