Dagger use change

[MicroChasm]

Using the dagger currently attacks the adjacent tile in a selected direction. Instead, to make the dagger easier to use, the player should move in that direction and then attack the next tile in the selected direction.

The place to change seems like: level.rs lines 657 through 669. Likely need to set result.pos, but also to check for both cases- a nearby golem and a golem one tile away.
