MDL-34290 repository_boxnet, boxlib use request timeouts

Browse Source 
boxlib receives additional argument as request timeout
repository_boxnet::get_file_by_reference respects request timeouts and downloads file into moodle only if it is image
also some improvements to repository_boxnet source display functions;
also do not cache result of request in retrieving of listing, user is unable to see the new files he added to box.
