LPS-46370 reorder FTL variables

I've reordered the variables (and removed those not strictly necessary). The only exceptions are:
  - defaultLatitude / defaultLongitude: They are used as a last resort when centering the maps (
    first center around the points; if there are no points, center at the user current position;
    if the position is not available, use defaultLongitude/defaultLatitude). As the default position
    is something the portal administration will want to customize, keeping the variables at the top
    will make it easier.
  - showEditURL: while usages appear at the bottom of the file, in the getAbstract macro, we have to
    initialize the variable before any call to the macro ocurrs.
