Enhance SwitchLampUnit to accept comparison type

[jsm174]

This PR updates the SwitchLampUnit to allow for a comparison type to be used when evaluating a match. Prior to this, matches occurred when the Value was equal to the Source Value.

This change allows incrementing variables to be used to turn on / off multiple lamps:

To support the ComparisonType enum displaying symbols instead of the enum value as a string, we created a new AttributedEnumInspector. This allows for overriding the displayed text with the Description attribute.

This new AttributedEnumInspector was then reused for the LampDataTypeInspector:

	public enum LampDataType
	{
		[Description("On/Off")]
		OnOff,

When looking at the following image, we see the drop down now shows On / Off instead of On Off:

Thanks!

Could you fix the white spaces, then I'll merge. :)

Fixed. Sorry about that. VS mac seems to have a mind of its own with CR/LF, tabs, spaces on new and existing files.

No worries!
