new splash screen

Add comments to UNIX Makefile regarding USE_UPNP

new toolbar icon for liunx/win fix #2518

On black toolbars, the new icon doesn't look very well.
Now the toolbar icon has again a transparent "B" for better style on toolbars.
Does not affect the mac client.
Signed-off-by: Jonas Schnelli <jonas.schnelli@include7.ch>

why:

- the current splash-screen has no referring to official images on - https://en.bitcoin.it/wiki/Promotional_graphics
- the current splash screen only exists in a low res jpg
- current splash screen looks dark and "hackish"
- new splash screen should generate positive, "trust-emotions".
- new splash screen gives the user infos about the running client.
- new splash screen can handle long messages (in a lot of - languages the text is cropped in current release)

- new size (x2) 400x312

- contains textual information about the client
- textinfos are dynamicly written to the pixmap

when -testnet is switch on, the splashscreen will show the bitcoin logo in testnet-color (as well as a text [testnet])

The tri-state nature of USE_UPNP isn't immediately obvious, so paste
the explanation from doc/build-unix.txt as a comment in the makefile.

new testnet ico file

Require strictly-standard encodings in mempool

Fixed download error

- that changes will be fine for Qt4 also

- this ensures our new splash screen and this will share a translatable
  string an remove the need for an additional translation

This allows the bool* type to be passed between threads.  Should solve issue #2402.

Bitcoin-Qt: remove " - " on empty title in BitcoinGUI::message()

qt: move export button to tabs

Use a uint256 for bnChainWork

Having the export button at the top was confusing people into thinking
the entire wallet was exported.

This commit moves the export button to the address book, receiving
addresses and transaction tabs separately.

qt: don't show rpcconnect command line option in help

Every block index entry currently requires a separately-allocated
CBigNum. By replacing them with uint256, it's just 32 bytes extra
in CBlockIndex itself.

This should save us a few megabytes in RAM, and less allocation
overhead.
