New contentView property

The FuriganaTextView class now has a new read-only property contentView to reference the underlying UITextView that dose the actual text rendering work.

The property will return a valid UITextView after the contents has been set.
Note: If the contents has never been set, contentView will return nil.

The previous text view customization properties are now deprecated, and will be removed in the next release. The properties include:

• scrollEnabled
• alignment

Please use the contentView to customize the text view instead.

Fix a bug when furigana attributed text encounters line break

In earlier versions, when furigana attributed text encounters line break, the furigana layout bounding rect may be incorrectly calculated to the combination of both lines, which may cause the furigana text be rendered at a incorrect position.

This version fixes this issue.
