Same keycode names as the on-screen editor to make it easier to identify the possible values. Xbox and PlayStation button names for familiarity. Saving configs handled by the Save and Exit buttons on the navigation bar. Currently known issues: - may be jumpy when cells reload or load onto the screen - loading a new configuration file does not update the value of the cells - loading a new configuration file does not update the "Controller configurator" item in the main Settings window - both of these are solved by closing and reopening the view controller for now
