Restructure processFuncRequest* function family:
- move a comment back from to GuiApplication to GuiView.cpp, so we have the comment in the place where we decide to process the func request asynchronously;
- rename dispatchDelayed to processFuncRequestAsync to have the same terminology as in the other processFuncRequest* methods;
- introduce a new function processFuncRequest to complete the set of processFuncRequest* methods. It is strange that for the normal processFuncRequest one should suddenly use lyx::dispatch. Besides, I think it is good that the whole GUI will dispatch funcRequests through GuiApplication::processFuncRequest from now on;
- use the slotProcessFuncRequestQueue to relay to processFuncRequestQueue;
- properly camelBump addToFuncRequestQueue;
- group the implementation of the processFuncRequest* functions;
- document the side-effect of processFuncRequestAsync.
