This adds a 32x32 16-bit icon to the bitcoin.ico file.
Though this realistically probably looks worse than the 32-bit
32x32 being displayed on a 16-bit monitor, it makes the nsis
setup exe deterministic in gitian output (go figure) which makes
the slight visual loss for users of very old monitors/computers
worth it.
The .ico file has changed in the following ways:
* Added 64x64 layer (max size for "Classic Mode").
* Added 256x256 layer (max size for Vista and 7).
* Removed copies with no alpha channel:
* Display depths lower than 32-bits are rare nowadays.
* 8-bit alpha channels in icons has been supported since XP.
* If the display depth is lowered, they look no better than the
downsampled versions that Windows automatically generates.
Tested various sizes on both XP and Win 7. It looks fine
(unchanged) on XP and downright sexy on Win 7.
