Freddy Updates to Swift 3.0

This release marks Freddy's adoption of Swift 3.

Swift 3's design guidelines have significantly impacted Freddy's API. We have updated the README and Wiki to reflect these changes, and will be publishing our documentation very soon. Take a look at these to see how interacting with instances of JSON has changed.

Notable improvements and changes:

• Our parser has gotten better
  • Allow leading zero with exponents
  • Fix a crash from attempted to read past the end of input when given incomplete input data
  • And more!
• JSON decoding has gotten better
  • Adds private method to decode terminating null into nil
  • You can now get a decoded dictionary from a JSON (see #176; note that we updated the API for these methods to match Swift 3 style)
  • Add serializeString function (Thanks @glennrfisher 👏 👏 👏 )
  • Added Int, Double, Bool conversion to String (Thanks @DarkSatyr)

Take a look to see what else we have been up to!
