use bindir instead of sbindir for non system tools

moved bat, bareos-tray-monitor, bconsole, bwild and bregex from sbin to bin directory.
Also moved there man pages from section 8 to 1.

Fixes a bug for building qt-console and qt-tray-monitor
(library ordering), so that they can be compiled,
even if an older version of Bareos is installed.
