Fix a strange warning in QtCreator:

/cvs/lyx/lyx-devel/src/frontends/qt/TocModel.cpp:356: warning: loop variable 'toc' has type 'const pair<std::string, shared_ptr<lyx::Toc> > &' (aka 'const pair<basic_string<char>, shared_ptr<vector<lyx::TocItem> > > &') but is initialized with type 'const std::pair<const std::__cxx11::basic_string<char>, std::shared_ptr<std::vector<lyx::TocItem, std::allocator<lyx::TocItem> > > >' resulting in a copy

/cvs/lyx/lyx-devel/src/frontends/qt/TocModel.cpp:356: use non-reference type 'pair<std::string, shared_ptr<lyx::Toc> >' (aka 'pair<basic_string<char>, shared_ptr<vector<lyx::TocItem> > >') to keep the copy or type 'const std::pair<const std::__cxx11::basic_string<char>, std::shared_ptr<std::vector<lyx::TocItem, std::allocator<lyx::TocItem> > > > &' to prevent copying

Easier just to use 'auto'.
