Subject: [PATCH] Made the arrow keys in DataGridWidget 'wrap around', so that
 when the end a row/column is reached, it goes to the next row/column.  The
 reason for this will become apparent over the next day or so.

Still TODO is revamp the base widget to accept and return an identifier
for which widget it is, since every widget/dialog in the debugger
currently assumes that there's only one type of each widget (so if there
are two DataGridWidgets, the returned signal doesn't know which one
to use).  Sorry if that sounds confusing ;)
