/*Description:
1) Adds a gravity command which gives an individual player a specific amount of gravity
which remains until player's death, in which case it is set back to normal (800).
2) Allows the players to buy their own gravities.
Credits:
v3x for some coding help which I figured out worked 3 months later. :)

我想加一个时间限制,多少秒钟后才能开始购买,然后就是购买后这种效果的能够维持多少时间...谢了
