Update editor pattern for all headstages and devices

[bparks13]

Based on the pattern first implemented in #459, add editors to all configure device nodes and to the device classes in configure headstage nodes.

WorkflowComponentEditor: This is the editor that is attached to the device node (e.g., ConfigureHeadstage64ElectricalStimulator).

UITypeEditor: This is the editor attached to the ConfigureHeadstage64.ElectricalStimulator property.

This only applies to devices that have a custom UI; devices such as Bno055 and TS4231V1 do not require either of these editors, since they are all using the GenericDeviceDialog to create a simple tab in the headstage dialog.
