Subject: [PATCH 01/41] Make change event always fire as the user interacts
 with the knob: - touch - wheel - typing (by binding to the "input" event)

Previously, typing did not update the knob until focus was lost (and
no change event was fired), and
using the keyboard arrows did not fire any change events.

Also move event triggering to val() and change() so it works always
in the same way and less duplication exists.

Subject: [PATCH 03/41] Make change event always fire as the user interacts
 with the knob

That is, when using:
- touch
- wheel
- typing (by binding to the "input" event)

Previously, typing did not update the knob until focus was lost (and
no change event was fired), and
using the keyboard arrows did not fire any change events.

Also move event triggering to val() and change() so it works always
in the same way and less duplication exists.

Similar to #130 but fixes an issue with `diplayPrevious`

+// Known Issues:
+//
+// * Patterns are not implemented.
+// * Radial gradient are not implemented. The VML version of these look very
+//   different from the canvas one.
+// * Clipping paths are not implemented.
+// * Coordsize. The width and height attribute have higher priority than the
+//   width and height style values which isn't correct.
+// * Painting mode isn't implemented.
+// * Canvas width/height should is using content-box by default. IE in
+//   Quirks mode will draw the canvas using border-box. Either change your
+//   doctype to HTML5
+//   (http://www.whatwg.org/specs/web-apps/current-work/#the-doctype)
+//   or use Box Sizing Behavior from WebFX
+//   (http://webfx.eae.net/dhtml/boxsizing/boxsizing.html)
+// * Non uniform scaling does not correctly scale strokes.

Subject: [PATCH 16/41] Allow choice of rotation; clockwise/anticlockwise

Fixes #105

Creates the `rotation` option that allows a setting of `anticlockwise`
(or 'acw') to reverse the direction of progression used by the knob. It
fully supports the clicking/touching and `displayPrevious`
functionality.

To facilitate extending this behavior to custom draw functions, arc
calculations have been factored out of `draw` into an `arc` function,
which returns the start and end angles, and a boolean denoting the
direction of the stroke.

Subject: [PATCH 24/41] Add UMD declaration

In order to require this plugin using Require JS or another AMD system
both this plugin and JQuery itself must be AMD-compatible. This PR adds
the Universal Module Defintion pattern from https://github.com/umdjs/umd
so it works as expected with AMD and with traditional methods of
inclusion.

Subject: [PATCH 25/41] loosen jquery version dependency

The previous jQuery version dependency tied the plugin to version 1.7,
not 1.7.1 or higher. I'm assuming this is compatible with 2.X too, so
loosened it to >=1.7. If it's not 2.X compatible, you could tighten it
to ~1.7 for all 1.X releases after 1.7
