Fixed all that shit and learned about GIT

The results are basically from the features and cleaning change but a
bit cleaner

Tried to fix bug with liftable

Cleaned up some liftable owner drag code

Features and Cleaning

- When players move a liftable to its goal zone
the liftable is removed
and the player gets +1 score and a new task
-
Liftbles now need a goalzone when they are created
- Liftables can now
only be carried by players instead of entities
