0.16.1
======
- Lots of bug fixes by Chris Wilson
- New feature: mouse scroll-wheel now feeds three arrow-up/down keys to the
  terminal if in the "alternate" mode.  The alternate mode is used by apps
  like vim, less, emacs, screen, etc.  This makes the scroll-wheel usable
  in a state that it was of no use before.

	Bug 426870 – vte often passes NUL to functions requiring valid unichar
