Update contrib/debian.

"USE_UPNP=-" is needed to remove UPnP support.

* Updates package description to note that blockchain now takes
  2+ GB instead of 150+ MB.

* Stop creating DB_CONFIG with DB_LOG_AUTO_REMOVE as that is set
  in Bitcoin itself now.

* Update changelog with 0.6.2 and the current updates.

Added 'immature balance' for miners. Only displayed if the balance is > 0

GUI: change verifymessagepage behaviour to match RPC-call "verifymessage"

GUI: move class HelpMessageBox to guiutil.cpp/.h

move class HelpMessageBox to guiutil.cpp/.h / add button to show Bitcoin command-line options (in RPC Console -> Information) / resize Debug window a little to allow for a non-breaking display of the welcome message with non-english translation

change verifymessagepage behaviour to match RPC-call "verifymessage" (input address, signature and message) / display messages in status label (remove message boxes) / resize window to make signature fully readable / change signature font to BC-address font (like in messagepage) / remove checkAddress() and place code directly in on_verifyMessage_clicked() / add visual feedback to LineEdits / remove AddressTableModel references, as they are now unused / add addr.GetKeyID(keyID) check

Translation: sync english translation master file with current master branch (2012-05-31)

incorrect openssl when compared to makefile

Testnet reset

Refactor: split CKeyID/CScriptID/CTxDestination from CBitcoinAddress

add client startup time as an entry to debug.log

Newlines in JSON strings are against the JSON spec,
so remove them from the script*.json unit tests to
make python's jsonrpc happy (json::spirit didn't care).

Bash completion for bitcoind(1)

This adds a field labelled 'Immature' in the overview section under the 'unconfirmed' field, which shows mined
income that has not yet matured (which is currently not displayed anywhere, even though the transactions
exist in the transaction list). To do that I added a 'GetImmatureBalance' method to the wallet, and connected
that through to the GUI as per the 'GetBalance' and 'GetUnconfirmedBalance' methods. I did a small 'no-op'
change to make the code in adjacent functions a little more readable (imo); it was a change I had made in my
repo earlier...but I thought it wouldn't hurt so left it in. Immature balance comes from mined income that is
at least two blocks deep in the chain (same logic as displayed transactions).

My reasoning is:
- as a miner, it's a critical stat I want to see
- as a miner, and taking into account the label 'immature', the uncertainty is pretty clearly implied
- those numbers are already displayed in the transaction list
- this makes the overview numbers add up to what's in the transaction list
- it's not displayed if the immature balance is 0, so won't bother non-miners

I also 'cleaned' the overview UI a little, moving code to the XML and removing HTML.

This introduces internal types:
* CKeyID: reference (hash160) of a key
* CScriptID: reference (hash160) of a script
* CTxDestination: a boost::variant of the former two

CBitcoinAddress is retrofitted to be a Base58 encoding of a
CTxDestination. This allows all internal code to only use the
internal types, and only have RPC and GUI depend on the base58 code.

Furthermore, the header dependencies are a lot saner now. base58.h is
at the top (right below rpc and gui) instead of at the bottom. For the
rest: wallet -> script -> keystore -> key. Only keystore still requires
a forward declaration of CScript. Solving that would require splitting
script into two layers.
