Add Item: Trident

[zicklag]

Hey folks! I got the assignment from @erlend-sh to make at least 2 weapons, so here's the first one. ( Thanks to @TekhnaeRaav for the idea to make a trident ).

The sprite is just a placeholder, of course.

I'm not 100% sure how you guys want to balance the weapons, but the trident currently swings faster than a sword, and the damage zone doesn't cover your own body, just the area in front, so it's got more of a spear behavior than the sword.

I think it measures more powerful than the sword in general, but still probably worse than most guns.

Also, I noticed that when laying on the ground and facing to the left, the sprites bounding box isn't quite right:

It turns out that the other weapons for the most part don't have a lot of empty space in the sprites on the x axis, so it's almost un-noticeable, but the trident has a lot of extra horizontal room for the stab animation so it get's harder to pick up the trident when it's facing left.

I'm assuming that should be tackled as a separate PR/issue, but if you want I can look into fixing it.

I just realized that you guys already had a set of item specifications to implement. Whoops. 🙃 That makes more sense.

Well there's this one if you want it, but I'll work on a couple of the ones from your list, too. 🙂

Edit: And I see there's already a trident in there, too, but with more advanced functionality. You guys have some good ideas. :)

I'll close this in favor of items from the existing specs.

Whoops, I forgot to link to the standard list of Items.

However, I don’t think we’ve implemented #149 so you can go ahead with that as well.
