Added Swiftify to the new Converters category
Added Swiftify to the new Converters category

* Project Name:
Swiftify

* Project URL:
https://objectivec2swift.com/

* Project Description:
Objective-C to Swift online code converter and Xcode extension.

* Why it should be added to awesome-swift:
Swiftify is the only available automated code converter from Objective-C to Swift 3.
It is actively maintained and constantly improved.
The project itself is not open source, but it has thousands of users.
This is the reason I don't have a GitHub link with a necessary amount of stars - please advise if this one can still be included.
I suggest to introduce a new "Converters" category rather than adding this into existing "Misc" category.
