0029367: Visualization - simplify interface of V3d_View and V3d_Viewer

The interface of V3d_View and V3d_Viewer has been simplified.
For the fields myDefinedViews, myActiveViews, myDefinedLights, myActiveLights were added appropriate methods returning the internal raw data.
Make the next methods deprecated:
IfMoreLights(), InitActiveLights(), MoreActiveLights(), NextActiveLights(), ActiveLight() and
InitActiveViews(), MoreActiveViews(), NextActiveViews(), ActiveView(), InitDefinedViews(), MoreDefinedViews(), NextDefinedViews(), DefinedView(),
InitActiveLights(), MoreActiveLights(), NextActiveLights(), ActiveLight(), InitDefinedLights(), MoreDefinedLights(), NextDefinedLights(), DefinedLight().

Remove deprecated methods added in scope of tasks 0029290 and 0028987 (Target Version 7.3.0):
SelectMgr_SelectableObject: Init(), More(), Next(), CurrentSelection().
SelectMgr_Selection: Init(), More(), Next(), Sensitive().
V3d_AmbientLight: one constructor.
V3d_DirectionalLight: two constructors.
V3d_PositionalLight: one constructor.
V3d_SpotLight: two constructors.
