Fixed some memory issues related with CGGradients

- Deprecated a couple of methods to follow the Apple naming guidelines.
(createNormalGradient and createSelectionGradient). Now use
newNormalGradient and newSelectionGradient instead.
- Fixed some memory management issues in some of the methods that
called the two above.
- Fixed an incorrect note in the docs (in methods createNormalGradient
and createSelectionGradient)

These changes remove all analyzer issues too.
