PriorityConnector

[niZmosis]

Does anyone else feel like the priority connector should be able to change to the last connector you interacted with? Something like if you call connector.activate() even if it's already active, or even a new function like connector.makePriority() which is more specific, be elegant?

Edit: Ended up looking into implementing something like it, went a different route by updating the Web3ReactProvider found in this PR
