Minor changes to local variable tables

Browse Source 
Split "edit local variable table" into "create" and "edit prior".
The motivation is to allow the user to make changes to the most
recently defined table without having to go search for it.  Having
table creation be an explicit action, rather than something that
just happens if you edit a table that isn't there, feels reasonable.

Show table offset in LV table edit dialog, so if you really want
to go find it there's a (clumsy) way to do so.

Increased the maximum width of a variable from 4 to 8.  (This is
entirely arbitrary.)
