Fire change event when user types in a new value or uses arrow keys

[xilocex]

Added s.cH(s.$.val()); @line: 146 so that the change event is fired when a user types in a new value for the input.

This was pursued in response to Issue #89

Added s.cH(v); @line: 511 so that the change event is fired when a user has the input focused and is using the arrow keys.

I added this @line: 166: s.cH(s.$.val()); to make the input value trigger the change event. Now it works great passing the input value to the callback.

@xilocex @j8 These fixes worked, but if you type more than the maximum amount of digits in the input field then the change event still won't fire (and the dial won't draw, either). e.g. if you have set a max of 99 (2 digits) and you type 100 (3 digits), then it will clamp to 99 but when the input field loses focus the change event doesn't fire and the dial won't redraw.
The same goes for the minimum (e.g. typing -1 when the min is 0)
Any ideas?
