Bitcoin-Qt: emit numBlocksChanged for changed reindex or importing state

- this allows our progressbarlabel to correctly update, when we
  finish a reindex or import, but do not get new blocks from other sources
Always print full hashes (tx, block, inv)
Make sure we always have a node to do IBD from

This introduces the concept of the 'sync node', which is the one we
asked for missing blocks. In case the sync node goes away, a new one
will be selected.

For now, the heuristic is very simple, but it can easily be extended
later to add better policies.
Add bytessent, bytesrecv and syncnode to getpeerinfo

move COPYRIGHT_YEAR to clientversion.h

- this allows usage of that information also in other places (e.g. splash
  screen)
use the new COPYRIGHT_YEAR macro in bitcoin-qt.rc

- this reduces the places, where we need to change the year further
fix bitcoin-qt.rc not showing up in Qt Creator
