graphics/goxel: modernize the port and update to version 0.11.0

- Lowercase all but the first word of the COMMENT, adjust LICENSE
  to match the source code headers
- Drop unused dependency and INSTALLS_ICONS knob, massage USES and
  USE_GNOME lists as needed
- Install more complete set of high-color icons, do not capitalize
  loop iterator variable
- Provide more elaborate port description, move WWW line where it
  belongs these days (in the Makefile) and chase redirection
- Assume maintainership since previous maintainer had stepped down

graphics/goxel: resurrect the port, unbreak against Python 3.x

Keep the changes at minimum to help Git track history better.

Remove some expired ports:

2020-12-31 emulators/fceux: Uses Python 2.7 version of scons, and Python 2.7
which is EOLed upstream
2020-12-31 emulators/gem5: Uses Python 2.7 version of scons, and Python 2.7
which is EOLed upstream
2020-12-31 emulators/nonpareil: Uses Python 2.7 version of scons, and Python 2.7
which is EOLed upstream
2020-12-31 games/freera: Uses Python 2.7 version of scons, and Python 2.7 which
is EOLed upstream
2020-12-31 games/glob2: Uses Python 2.7 version of scons, and Python 2.7 which
is EOLed upstream
2020-12-31 games/marsnomercy: Uses Python 2.7 version of scons, and Python 2.7

2020-12-31 graphics/uniconvertor: Uses deprecated version of python

Revert r559792 to unbreak INDEX and bulk -a
It seems a lot of reverse dependencies were missed

With hat:	portmgr

Remove most expired ports that depend on Python 2.7:

Exceptions are:
- mail/mailman, our listservers still use it
- www/chromium, solely because of popular demand,
  upstream is (slowly) working on porting it to Python 3
- ports that have actual patches for Python 3 against
  them (Cinnamon and a few unrelated other ports)
- llvm70 and qt5-webengine because they seem to have a lot
  of dependencies which need further analysis
- sysutils/uefi-edk2-bhyve because bhyve seems to use them
- python2 and python27 themselves

I'm sure there will be complaints, but the nice thing about
a version control system is that we can revert and adjust things.

Update USES=scons to specify scons of Python 2

- While I'm here, convert emulators/gem5 and games/marsnomercy to USES=scons

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.
