* add TOCropViewController as dependency to replace RSKImageCropper
* implement TOCropViewController
* Fix behavior when using `freeStyleCropEnabled` and setup proper crop aspect ratio by calculating `width` and `height`
Why?
* Ruby uses `"` quotes when interpolation is required. Using `'` will mean `v#{version}`
is used directly rather than providing the version number.
Changes:
1. User Ruby string interpolation when setting the tag version for the source.
