dev112 - prepare for advanced arp macro

Browse source 
this new advanced arp macro offers more flexibility and reduces code duplication
it allows you to set each step of the macro to either relative or fixed mode
(instead of just one mode for the entire macro)

the UI is still a work in progress and doesn't work well

this change is big and may break things! further fixes incoming
