UI: Ropsten/custom chain considered as Mainnet

[chevdor]

I am running parity using --chain ropsten.json

In the UI, parity shows a green label that usually means MAIN net.
In the contracts and accounts tab, I can now see a mix of accounts/contracts from Homestead and Ropsten => the Ropsten accounts/contracts do show up, but the Homestead ones as well.

The Network ID should probably be used to identify the network and store/filter the accounts/contracts.

I think the color code for the network is a good idea and I would propose to extend it as follow:

• Homestead / mainnet => green (unchanged)
• Morden / Ropsten / testnet => cyan (red is a contradiction, red = risk, testnet = no risk )
• other / unknown networkd id => yellow

Fixed in master yesterday.

Still happens when using a chain file, but not using --chain ropsten (or --testnet)
