Add support for BSC

[php4fan]

On my Android phone, I have MetaMask installed.
I am connected to the BSC (Binance Smart Chain) network, with id 56.

When I try the demo and connect to the wallet and come back, I get this:

Why do you even need to support a network at all? As long as it's an EVM compatible network, can't you just "agnostically" perform all the actions with whatever network I have selected in the wallet?

Either way, BSC is popular enough that it deserves being supported, whether that requires any action or not.
