`*` hotkey should suggest a size for the array based upon next DataVariable or end of Section/Segment

[plafosse]

When you hit * hotkey on a variable it should look for the next DataVariable or end of Section/Segment and suggest an array size that would fill that region.

Suggested enhancements:

1. if user hits * on a thing of type $type (with no selection range) and there are a bunch of $type things following it, pre-populate the dialog with the range of those same-typed things (might also consider having it offer a "both ways" button so it would work even on a datavar in the middle of a sequence of them). Basically, act the same as if they'd hit * with all of the adjacent same-type datavars selected.
2. if a user enters a function name into the type field, use the type of that function for the element type, as if they had entered a function type
