4.25.0

This updates the FAN SDK to 4.25.0 for both Android and iOS.

iOS 4.23.0 Android 4.22.0

ios 4.23.0 now requires xcode 8 because they use a class property in a public header.
ios 4.23.0 also seems to fix that whole situation where we had to replace the ld64 linker in our AIR distribution to use it. According to their changelog: Reverted LTO-built library due to compatibility issues compiling with older Xcode versions is probably what fixed it. Just a guess.

iOS 4.22.0 Android 4.20.0

update FAN to 4.20 Android and 4.22 iOS

Using this on an iOS build may require you to update the `ld` linker in your Adobe Air SDK distribution at `{AIR SDK directory}/lib/aot/bin/ld64/` by copying /usr/bin/ld` to that directory and renaming it `ld64`, overwriting the one there. It seems that the linker provided with Adobe AIR is outdated, and the old one gives errors about the FAN SDK not having slices for arm64 and armv7, even though it does.
