dapp-template fails to load in browser without MetaMask installed

[sentientforest]

Running the dapp-template with npm run dev and loading the local server in a browser that does not have MetaMask installed results in a blank black page and the following error in console:

 Uncaught Error: Ethereum provider not found

Tested in Chromium on x86_64 Linux.

Suggest catching this error and displaying a call-to-action with link for the user to install MetaMask to use the application.
