re:squake

In this release I've ported a new movement mechanic from the original squake mod: sharking — ability to glide across the surface of water by holding jump. It allows you to quickly gain additional speed and cross large bodies of water without a boat.

Other improvements include:

• Keybind to toggle the mod
• Server no longer crashes with this mod installed
• Taking fall damage no longer resets player velocity if the mod is installed on both client and server
