Global trigger Ignite Entity/TNT

I like this feature, Unfortunately it's already possible with the Triggers. There however isn't a block to trigger those events, unless you count the [Trigger game event] block, though I haven't tested with that enough to know if it will allow for that.

"player right clicks on entity" and "player right clicks block" 
    (if item in mainhand = flint and steel) 
        {your code}
