Fix mention_map and hiders causing a light source error

Browse Source 
Prevent glyph change messages while loading a level file.
Otherwise a monster hiding under an item triggered a vision recalc
before light sources were linked to their sources, leading into

getlev -> hide_monst -> hideunder -> newsym -> show_glyph ->
 pline_xy -> vision_recalc -> do_light_sources -> get_obj_location

Add in_getlev program state variable, analogous to in_mklev
