Bluff Bash Ultra 4 1.76

UPDATE 1.6

Added a new rock section to the chicane at the end as an option line - take the longer way through the sand, or some risk through an extra rock section for a short cut.

Reworked the big hill coming out of the sand to try and make both sides a little more competetive.

Misc. tweaks to terrain to make turns flow a little better, add some berms here/there, lot of smoothing, and building some new terrain to help block track cuts and maybe make it the track feel a little less empty...
