Adding systemd service for bitcoind, to provide for a simpler out-of-the-box experience. Configuration file is /etc/bitcoin/bitcoin.conf. This file is a copy of the sample configuration file. The service user 'bitcoin' is added during install. Its homedir is in '/var/lib/bitcoin'. bitcoind.service is disabled by default to allow the user to configure it, before starting it the first time. On package purge, the 'bitcoin' user as well as its homedir is left intact, to not accidentally remove a wallet or something of equal importance. Instead the user is presented with information on how to perform the cleanup manually, after making sure all important data has been backed up.pull/585/head
