add effector with capability to break nodes

[lolbinarycat]

brought up in #543, this would greatly increase the types of automation possible with mesecons.

unsure if this already exists in another mod.

the node would have a single inventory slot with a tool.

when given power, it would calculate mining time for the node it was facing based on the tool it contained.

after the calculated amount of time had passed, calls minetest.dig_node and adds wear to the contained tool.

the item is dropped where the node previously was.

Apart from the dig time, the node breaker in pipeworks already does this.

This feature is more work to implement properly than you might think, because you need a fake player for on_dig callbacks and similar.

(Also mesecons currently doesn't do anything with items, so it wouldn't really fit in. Disclaimer: That's just my opinion. I'm not a maintainer.)

thanks! that basically answers my question.

closing this as out of scope/covered by other mods.
