Cleaned up `CMakeLists.txt` files in subdirectories so that the minimum reqiured
version is set only at the beginning of the top-level `CMakeLists.txt` file

Fixed UnidentifiedShape I/O (in particular, the restore part) and introduced a new unit test for GeoUnidentifiedShape writing and reading

Modified:
* GeoModelExamples/HelloGeoRead/CMakeLists.txt
* GeoModelExamples/HelloGeoReadNodeAction/main.cxx
* GeoModelExamples/HelloGeoWriteReadWrite/main.cpp
* GeoModelTools/GMCAT/src/gmcat.cxx
* FullSimLight/include/MassCalculator.hh
* FullSimLight/src/FSLDetectorConstruction.cc
* FullSimLight/src/MassCalculator.cc

Sarka Todorova correctly noted that the public loaders should return
a const 'world' volume, so a const pointer to the GeoVPhysVol.

I added constness to both the GeoModelRead::buildGeoModel() and to the
new loadDB() helper methods.

I then remove the constness in the visualization code, internally,
otherwise it's more complicated to manipulate the geo tree.

The example now compiles three executables:

1) main1, which uses the loadDB helper to pick the 'world' volume from
   the input .db and loop over its children;

2) main2, which uses the 'getReaderDB' helper to get a reader object,
   with which it reads data rows from the input .db file. It then picks
the 'world' volume from the same .db file with the 'loadDB' helper and
loops over its children;

3) main3, which performs the same operations than main2 but without
   using the new helper functions. It uses the lower-level GMDBManager
and GeoModelRead directly. That shows how to use those to users who
need to perform lower-level operations.

Introduce new I/O helpers, new I/O tests, and a 'loglevel' to steer the verbosity; and remove old cmake options
