#1 Start sqlcockpit from a different cwd

[Slaven Rezic]

It's not possible to start sqlcockpit from another
directory than
the directory containing sqlcockpit itself. This can
easily be fixed
by using $FindBin::RealBin. See the attached patch. I
may missed
some places where $FindBin::RealBin should also be
used, but
at least it is sufficient to get the application started.
