CLI: Permit options be passed to hyper/electron bin

[chabou]

We need to permit users to pass options directly to hyper/Electron bin.

For example: hyper --ignore-gpu-blacklist

Hyper currently uses args to handle command-line arguments at runtime, but as far as I could tell, args has no way of handling unknown options. We'll either need to include all of the options that can be passed to Electron manually, or use a different implementation for handling CLI arguments.

In particular, yargs seems to have a way of routing the arguments through custom middleware before running the command associated with them.

Totally opened to replace args by something else :)
