[gSender Issue#230] Reordering of macros isn’t persistent

I modified MacroItem.js to include macro.rowIndex in addition to macro.name in the display to see what is happening (or not happening). If I start with no macros in gSender (manually deleted all of them) and then import a set of macros I have this macro list:

!macro-ordering-1

I then grab the Probe Edge Top (2) macro to the top of the column as so:

!macro-ordering-2

it looks like it reordered the macros. However, if I reload the page the list of identical to the first image. After the proposed change, making the same reordering results in:

!macro-ordering-3

both immediately and after reloading the web page.
