queueing

[BelfordZ]

Explanation

What is the current state of things and why does it need to change?

Currently, dapps must keep track of what metamasks selected network is, and switch the network appropriately. We recently added a selectedNetworkController that keeps track of what dapp has requested what network. This PR adds some middleware that will automatically prompt the user to switch metamasks network if the saved network for the dapp doesnt match. It also adds a queue, which will cause requests which require confirmations to be processed in a first-in-first-out manner.

The queued request controller provides this api mechanism and serves as a place to interate on the queueing implementation.

The selected network controller is updated to provide a proxy provider - that is, a provider that will be swapped out based on the dapps network selections.
