- added the help button (?)

• in some situations, the help button will be available
• pressing opens the helper, a new window that shows you tutorial videos for specific actions in the game

- added ROLLER COASTERS !

• roller coasters are unique rides that let you create rail tracks very easily by right clicking and using the up and down arrow keys
• the helper is available while editing a track
• rail tracks can go around and above objects and path tiles!
• once a track is complete, wagons circulate independantly along the rail track
• each wagon can be occupied by one (1) customer
• the fun given by roller coaster depends on the length of its track
• objects, path tiles and waiting lines can be placed under rail tracks, but not inside
• the first roller coaster added is called the Lavamatic, costs 30 000 soul shards and has a reliability of 75

- tweaked ride prices to make early game more interesting:

• ferris wheel : 10000 (prev 15000)
• star flyer : 20000 (prev 13000)
• to-be-haunted mansion : 8500 (prev 8000)

- changed the way customers choose which ride they want to go to in order to balance attendance between rides

- rides now loose health two times slower

- the park's cleanliness stat now increases 70% slower relative to the amount of trash piles in the park

- fixed cleanliness stat being at 0% if 0 object were placed

- trash piles now automatically disappear after 90s

- updated labels for deleting object to indicate a selling price rather than saying it's going to be destroyed

- updated skybox to adapt vertically

- selector and selection boxes shouldn't clip into objects anymore

- loading parks with a lot of path tiles should be faster

- switched the next and skip buttons in the texbox and made the skip button darker in order to highlight the next button
