Make text view uneditable when disabled

This fixes a bug where the text view was still editable when disabling
the view.
Fix bug where view would get messed up

This would happen when the utility button image was set multiple times
in a row to either an image or nil.

Use UI_APPEARANCE_SELECTOR

This is used for buttonTintColor, buttonTitle, placeholder, and
utilityButtonImage.

This project was extracted from another project where it was called text
bar and not compose bar.
Fix whitespace
