Adding the restart eye of ender to parkour

[iGaboDabo]

Duplicate suggestion, go vote for that one to see this being implemented!

Parkour UI

Idea: In the new UI, have an option where you can teleport to the parkour starting place. More information: If you miss a jump, you have to walk all the way back to the beginning or to the hill shortcut and start over again. Would be nice if you could just teleport back to the beginning.
