Minor issues with "last block" indicator

[ghost]

Server Last Block: {} ({}) | Server Version: {} | Wallet Last Block: {}

• It doesn't show all the time (it appears, then it disappears again), but when it does appear, the entire GUI flashes very quickly, which isn't good
• Terminology
  • It's not clear which Server Last Block figure is for Counterparty Server and which for Bitcoin (in theory you could connect to another server and have CP be ahead of Bitcoin Core). Assuming the second value is for the blockchain, I'd prefer Last Block: {} (Blockchain {}) | Server Version {} |
  • Wallet Last Block: should we change this to Counterparty GUI Last Block (or counterparty-gui, since that's what's being used throughout)
  • Maybe Server Version doesn't need to be displayed (e.g. it could be shown only in Support > About?): if the version is different from the client, then client may not be able to connect in any case. Once connected, the user then doesn't really need that info, I suppose.

I update the text. It is now 'Server Last Block: {} | Wallet Last Block: {}'.

@Rippler, the "flashes" problem with the status bar always here ?
