guns, levels, and gameplay improvements

This is a BIG update that adds a LOT of stuff to the game, so it'll be pretty hard to cover everything, so i will only mention the BIG and IMPORTANT stuff.

firstly, i added a full body rig system to the game, now you have an actual body and hands that hold your weapons instead of having them fly midair.

there is also now a brand new, massive, big, insane weapon, meet THE SHOTGUN, it has a very low range, but INSANE damage that EVAPORATES everything that stands in your way, however, there is also a new mechanic that adds recoil that depends on the weapons gunpower, so the recoil will be big.

i added a new level with an easter egg

fixed parkour so you cant just climb everything, the camera is also now animated so you'd know when you wallrun.

you also now wield a KNIFE, using right mouse button you can slash with it, it has high damage, no recoil. but it doesnt stab far either.

that's pretty much it, aside from smaller things like bugfixes, e.t.c.
