There is some advantage to implementing these as properties as well,
for consistency.  However I think that implementing text_change as a
signal has the advantage that one doesn't have to extract the whole
text buffer in order to update the "property".  In other words,
text_changed allows notification of the change, rather than a
replacement of the whole "text contents" property.  Also signals allow
us better control of global notification.  I think properties should
be OK for the TABLE stuff.
