"Help -> Man Page" opens MANDIR/fotoxx.1{,.gz,.bz2} rather than DOCDIR/fotoxx.man (there's no need to install a duplicate file)
New feautures:
- read also .bz2 compressed text files (using bzip2)
- "Help -> Man Page" reads the man page directly from MANDIR
In the GUI, "Help -> Man Page" can now read MANDIR/fotoxx.1{,.gz,.bz2} file.
There is no need to put fotoxx.man into DOCDIR, the compressed man page fotoxx.1.gz can be used instead.
