breaking up the riderequestofferform into a search form, submit form w/ subclassing
fixed: search offers uses the view that searches riderequests
finished splitting riderequestofferform into different forms:
	riderequestoffersearchform - search for eithe requests or offers
	riderequestputform - create a new ride request
