MOAR CHANGES: Adding start and stop graduations to the dial widgets, as well as a easier way to configure the dials. Lastly, updating all the graphs to use auto-Y-scaling region selection.

Additionally, the configuration options for the dial widget has been reworked to make it easier to determine what the available display stylings are. This required adding the facility to have a dropbox/combobox as a configuration option within `designer.js`. Furthermore, there is now a additional variable in the widget configuration object (`optionsdata`) that can contain a set of `value` <-> `Ascii Description` mappings, so a raw value like `8` can be easily mapped to a human readable description: `[8,    "Light blue <-> Red, Zero at mid-left"]`.

Lastly, I updated the rest of the graphs to use x only scaling when zooming.
