Up to [LON-CAPA] / loncom / interface / statistics

Continue switch to navmaps.
lonstathelpers: &render_resource now expects navmaps resource
    renamed ProblemSelector to problem_selector and refactored it to use
    navmaps.
    refactored get_prev_curr_next to use navmaps AND modified it to return
    the navmap object.
lonsubmissiontimeanalysis: refactored to use navmaps and to pass new
    parameters to loncoursedata::get_response_time_data
