Delete a wrong delegate method declaration
Fixed when user insert the new sections, the cell will display with a blink animation at the first operation.
Handle the larger UICollectionView in iOS 8.

In addition to increasing padding in PSTCollectionView, this also changes PST class registration so that it does an all-or-nothing superclass replacement of the PSUI*_ classes. This prevents instances like the current case on iOS8-beta 5: PSUICollectionView_ has a superclass of PSTCollectionView, but the other types (e.g. PSUICollectionViewLayout_) had their superclasses replaced with UICollectionView*. This mixed mode is dangerous, as the PST* implementations rely on other PSUI*_ types maintaining their PST* superclasses.

Fixed the display bug, when called the insertSections:
Added explicit type conversions to remove warnings when using strict warning settings.
Used MAX instead of fmax so that we are not converting between doubles and floats on 64-bit builds.
Reverted to fmax using tgmath.h to handle 64-bit builds.
one more 64 bit fix
