Subject: Modifier key profile condition (#487)

* update Frontend options on modifier change

* add modifier key profile condition

* use select element for modifier condition value

* support "is" and "is not" modifier key conditions

it's never null in that function

* pass element on rather than assigning to this

* rename event

* remove Firefox OS key to Meta detection

* hide Meta from dropdown on Firefox

* move input type
