Setting parameters for battery levels

[outon]

Setting three new parameters to change battery levels when defining plugin

• Parameter Mode2: Battery Level Full can be set between 75% and 99%
• Parameter Mode3: Battery Level OK can be set between 40% and 75%
• Parameter Mode4: Battery Level Low can be set between 10% and 25%

Example: 75, 40, 15

• Battery level is Full when is greater than 75
• Battery level is Normal when between 40 and 75
• Battery level is Low when between 15 and 40
• Battery level is Empty when is less than 15
