* Revert changes to programs/dtsearchpath/libCliSrv/UnixEnv.C
introduced by c3cb5b8aa6
that could have produced disappearing Application Manager
icons on FreeBSD
* Introduce SearchPath:useSystemPath() virtual method to tell
dtsearchpath to leave some environment variables alone.
It is currently overriden for FreeBSD only if the MANPATH
is empty (system default). Other operating systems
might want to override it if they prefer to have distribution
specific control of a search path in effect.
* Symlink /usr/dt/share/man to /usr/dt/man for FreeBSD
This allows dtsearchpath to actually include /usr/dt/man
in the MANPATH when MANPATH override is in effect.
