Fix/testnet support

[plondon]

TODO

• Fix kvstore entries
• Fix send
• Fix add wallet account
• Disable other currencies?

Description

Pull in network from wallet-options

Change Type

• Feature
  Added testnet support

• Bug Fix
  ~~1. The var network is assigned with settings.NETWORK_BITCOIN but we are using NETWORK as the name in config/index.js so its value is always undefined. Renamed NETWORK as NETWORK_BITCOIN

2. Passing network as a param in actions.auth.register() function~~

Testing Steps

1. Change wallet-options-v4 in config/ to use testnet instead of bitcoin network.
2. Run yarn start:testnet
3. Should successfully create a wallet

Code Checklist

• Code compiles successfully (verified via yarn start)
• No lint issues exist (verified via yarn lint)
• New and existing unit tests pass (verified via yarn test)
• README.md and other documentation is updated as needed

I don't remember if kvstore works with testnet addresses. Have you tried that @plondon ?

[plondon]

I actually need to check this more because if I set a kvstore value (e.g for shapeshift state) then login breaks.

kvstore works now

Overall looks pretty good. Two feature requests though.

1. Can we change the Webpack dev server wallet options to proxy to return wallet-options-v4.json with the network set to testnet. That way we dont have to manually modify the file.
2. Similar to v3, we should have some sort of red warning banner in the header of the app that indicates testnet is in use. Hopefully people wont lose funds then.
