core: remove includes in .cpp, if header is already in .h

- example: if util.h includes stdint.h, remove it from util.cpp, as
  util.h is the first header included in util.cpp
Remove Wallet Tools

We already have the exact same funtionality in /contrib/bitrpc/bitrpc.py

If we really do need standalone scripts, then I'll write something to
pull it from that file, rather than having duplicate code.

Forgot to remove wallet tools from index.

I was merging change this every time before generation of
the doxygen developer docs (https://dev.visucore.com/bitcoin/doxygen/)
but there's no reason why it can't just be merged upstream.
qt: show all units in send confirmation

Make users accustomed to the other subdivision units (mBTC, muBTC)
by showing the total amount in all units in the confirmation dialog.

This was recently raised on the mailing list and could be a preparation
for switching over the default unit eventually.

qt: keep a list of requested payments

Keep a list of requested payments in the Receive tab so that a user can
recall previously created requests after closing their windows.

Currently this list is not stored between bitcoin-qt sessions. This can
be implemented later, but it is not clear where it should be stored as
I don't think it belongs in the wallet (maybe in QSettings?)
