net-irc/quassel: new init script revision to prevent privilege escalation.

This commits adds two new files,

 * quasselcore.init-r1
 * quasselcore.conf-r1

that are as yet unused. The init script has been entirely rewritten to
use modern features of OpenRC, and uses the default start/stop
implementations, so it is greatly simplified.

To avoid the "chown" problem in bug 603414, the new init script and
conf file do not allow changing the quassel user on the fly. Instead,
the "quassel" user created by the ebuild is used unconditionally. As a
result, there is no need to fix permissions when the daemon is
started, and thus no need to change ownership of anything. A further
permissions-related simplification logs to syslog instead of a file by
default. Since the daemon runs as a restricted user, that avoids
another set of permissions (on the log file) that would need to be
mangled.
