We now have a page for making requests directly with query string
parameters. For example, you can make an `eth_getLogs` request by
navigation to:

`[test dapp path]/request.html?method=eth_getLogs&params=[{}]`

This can be useful for testing RPC methods not covered by the test
dapp functionality, or for e2e testing (especially on mobile, where
clicking elements on the page can be challenging).
