[PARK-54] Move 'Next Step' button left, add cancel button

Request was to move the 'Next Step' button to the left and add a cancel button on the right (plain blue hyperlink). 

( I think it may make more sense to have the save details / next step button on the right, to echo the idea of 'moving forward', but I've left it as per the directions. )
