Fix one crash and compile issues

Don't access FileName in constructWindowTitle when we don't have a file
at mCurPos. That's what crashed us randomly!

Also (yes, I know, should be a separate commit) fix warnings about
implicit fallthru's in switch statements. The one in SmDirModel actually
was a bug, the one in tabChanged is just a nuisance.

Also (again), shuffle header inclusion in SmGlobals so Xlib and QT don't
clash.
