JSON Spirit updated to v4.06
Switch to using raw_utf8
Add separate bitcoin-rpc client

This adds an executable `bitcoin-rpc` that only serves as a Bitcoin RPC
client.
The commit does not remove RPC functionality from the `bitcoind` yet,
this functionality should be deprecated but is left for a later version
to give users some time to switch.

qt: rework "receive coins" workflow
qt: remove verify/send message and send coins from address book

These no longer make sense in the new workflow. It's less
clicks to reach sign/verify message from the menu. And sending
from the address book is one kind of automatic address reuse
we're trying to avoid.
qt: allow dragging, copying and saving QR code

Add context menu and drag handling to QR code widget.
qt: add message field to SendCoinsRecipient

Also update URI parsing to fill in this field.
Note that the message is not currently used in any way with the client.
It should be stored with the transaction.
qt: use SendCoinsRecipient for payment request information

This brings some symmetry into the design by using the same object
both for incoming URIs that are parsed as for outgoing URIs that
are formatted.
qt: move bitcoin URI formatting to guiutil

Follow the same pattern as the parseBitcoinURI function.
qt: show payment information in one text area

Simplifies the dialog (makes it look less crowded) as well
as the code and makes it possible to copy multiple fields at once.
Also format bitcoin URI as URI, add copy button for URI.
Add test for monetary value formatting

Tests for issue #3126.
This problem pops up after upgrading json-spirit.
