BGE: Cleanup KX_BlenderSceneConverter.cpp iterators, checks, indentations and spaces with uncrusify

"(*it).second" become "it->second" same as "first"
"!(it == list.end())" become "it != list.end()"
"if (ptr == NULL)" become "if (!ptr)"
And a run of uncrusify on this file to fix indentation and spaces.
