Create wallet info screen accessible from settings

[aguycalled]

Create a WalletInfo screen accessible from settings which shows wallet information like:

• Whisper Wallet version
• Navcoin-js version
• wallet name
• connected server
• block height (accessible through wallet.lastBlock)
• network

related to this issue, would it be a good idea to show the name of the wallet at the home page of that wallet? given whisper is multiwallet based and the function of re-opening last wallet used, users can forget what wallet was used last time and therefore unsure of which wallet is being used.

yes good idea
