Yo, i'm back

This update introduces 2 new tracks to race on, one for each cup:

This update includes a few changes to Tidal Town and Glacial Halls

• Added some directional arrows to the second half of the track
• Slightly moved the boost panels in the last section of the track

• Added directional arrows to a few different sections of the track
• Adjusted the iceberg section to have smoother terrain
• Removed the FOF in the iceberg section (replaced with springs instead)
• Blocked off some sections in the castle to make the intended layout more clear

• Changed the snow on the wall section to weak offroad
• Increased the width of the wall section
