Various tweaks

Changed the code that generates cross-references for pre-labels to
ignore labels in regions with non-addressable parents.  Also, changed
the code that complains about references to labels in non-addressable
areas to ignore pre-labels, because it was complaining about references
to pre-labels on region starts that were followed by a non-addressable
region start.

In the address region edit dialog, split up the descriptive text for
the "resize" option to make it easier to see the new end offset and
length.  It doesn't look quite right because it's not using the mono
font like the text near the top, but it'll do.

When multiple lines are selected, the Info window now shows the first
line/offset, last line/offset, and bytes spanned by the selection.
This is helpful if you're trying to figure out how big something is.
