Removing left (or right) view when set
When changing either the left or right view we currently need to write:

leftView = nil leftView = view

It would be nice if we can simply write:

leftView = view

What do you think about this?

I also took the liberty to updated the Example using Swift 3.0 and Xcode 8.

Update textView properties on didSet

Several textView properties are not updating properly, because they are only read at initialization (and it's impossible to set them before the view is initialized).

This PR updates these properties to set themselves in didSet, so they will work as expected.

Resolves issue #25.

Fixed incorrect calculation in roundHeight method.
The calculation below which is found in the roundHeight() method of ALTextView seems to be incorrect. It should be using textContainerInset.right property instead of textContainerInset.bottom to calculate width for the bounding size.

let boundingSize = CGSize(width: frame.size.width - textContainerInset.left - textContainerInset.bottom, height: .greatestFiniteMagnitude)

Make ALTextInputBarDelegate identical to UITextViewDelegate

Hello Alex,

I remove the ALTextInputBarDelegate's textViewShouldReturn method and replaced it with the textView(_:shouldChangeTextInRange:replacementText:) as to reflect the UITextViewDelegate.

I have thought about a solution to not break code that already use the ALTextInputBar library but nothing came to my mind that seemed correct. One could call both the textViewShouldReturn and the textView(_:shouldChangeTextInRange:replacementText:) but this leaves the question which of the delegate methods is given priority in the case that one returns false and the other true.

Kind regards, Jessy

Xcode 10 / Swift 4.2 upgrade.
This PR:

Updates to Xcode 10 / Swift 4.2 compatibility.

Removes 3 core library source files from the testing target. Those files were likely added on accident, but it was preventing compilation of the test target. Those files will be imported into the test target like any other library.
