Keep in mind that the character menu can currently be opened when transformed as a humanoid. I'm only changing it because its the functionality in the character menu is not affected by humanoid status.

Transformations usually alter the player's stats, so we want them to be able to view them in the character menu. Disregard my previous concerns about bugs. Transformations don't touch primary stats, so we're free to modify them.

Restricting powers makes sense because transformations will have their own set of powers. The less restricting we have to do, the better.
