Remove rest of OptionsGlobalProperties.

Remove rest of OptionsGlobalProperties.

Replaced plot type handling with a separate AnalysisDataPlotSettings
class, which is now declared in the same module where the actual
plotting is implemented.

Interaction with the existing output_env_t structure (that is needed for
passing to legacy methods) could be improved, but that is internal and
local to a few classes, so it's easy to fix later.

Also fixed a MSVC-specific warning in basicoptions.cpp that for some
reason appeared, although that part of the code was not touched.

Part of issue #839.
