Fixed deprecations

- Replaced #317 - `NSGregorianCalendar` deprecated in iOS8 and Mac OS X 10.10 replaced with `NSCalendarIdentifierGregorian `. Could not check for availabilty of the constant directly, since it is defined earlier, but not available for iOS
- Replaced #312 - `aslresponse_next` and `aslresponse_free` deprecated, replaced with `asl_next` and `asl_release`
- Updated a Podfile.lock for the CaptureASL project
