Fixed a problem with Zoom plugin in python 3

- Zoom plugin now shows a "Refresh Interval" rather than a "Lag Time"
- zoom image is updated within the interval (default 20 ms)
Fixed an issue that preventing resizing gtk widgets

- use of set_size_request() in gtk forces a minimum size
- implemented proper widget callbacks for negotiating desired size
Redraw optomization moved into base class

- moved common redraw optomization into base class
- changed optomization algorithm, now does not defer redraw longer than
    redraw_lagtime.  This can be set with set_redraw_lag() (but may become
    a general setting like most others).  Panning now feels a little faster
    overall.
Bumped release number
Ginga gets a Matplotlib backend!

Ginga can now render to a Matplotlib FigureCanvas.  The performance using
this backend is not as fast as the others, but it is acceptable and opens
up huge opportunities for overplotting.
