Beta 2 updated!

I just re-uploaded the beta 2 version of "Black Pharao" with the following small fixes:

- debug console doesn't close on any more
- added "Unlock wallet" and "Lock wallet" to the "Operations" menu  (only shown if the wallet is encrypted and depending on current lock state)
- "Change Passphrase" only present if wallet is encrypted in "Operations" menu.
- "Encrypt Wallet" only present if wallet is unencrypted in "Operations" menu

Simply re-download the beta 2 version if you want those fixes, don't do it if you don't care.
