This PR overhauls the skateboard system and introduces some new things. First there are now more skateboards, the original craftable skateboard is still in but now there is a better "pro" version. Additionally there are hoverboards, (one of them is an admin hoverboard). These two new boards (not the admin one) can be won from arcade machines as prizes.

You can now hold your skateboard, and put it in your backpack. You can also do neat tricks like an ollie and grind on tables with it. Bumping into things has been reworked so you no longer get knocked into oblivion if you even dare to tap someone or something. You will now take stamina damage. Though if you are at low stamina you will still fly off.

If you want me to try and increase the speed I might be able to (with some help).

Like you have mentioned; they're really slow for some reason.

Any way to speed these up? I think a lot of people might be unhappy that these new boards are quite a bit slower (just a bit faster than walking)
