Changed users of cell->connections_ to the new API (sed command)

git grep -l 'connections_' | xargs sed -i -r -e '
	s/(->|\.)connections_\["([^"]*)"\] = (.*);/\1set("\2", \3);/g;
	s/(->|\.)connections_\["([^"]*)"\]/\1get("\2")/g;
	s/(->|\.)connections_.at\("([^"]*)"\)/\1get("\2")/g;
	s/(->|\.)connections_.push_back/\1connect/g;
	s/(->|\.)connections_/\1connections()/g;'
