Fix continuation after skipping key cert LS stores for floodfills
that don't support them; ditto big leasesets

as suggested in https://lists.torproject.org/pipermail/tor-dev/2014-March/006576.html

 * NetDbRenderer: Adjust debug floodfill estimate
 * StatManager: Don't start thread for an empty config
 * StatisticsManager: Don't publish client tunnel stats
 * Log tweaks

     and '5c131297d763f8953029fea257681d55f2103aaa'

Spotted in the FreeBSD Port (http://svnweb.freebsd.org/ports/head/security/i2p/files/patch-installer__resources__postinstall.sh?view=markup)

Moving the pre-release checks to a new target (to be run at the very start of
"release")

* Hash: Cleanup of cached hash
* NetDB: Randomize returned DSM timestamp
