some more work on org tables

[prayner <prayner@xxxxxxxxxxx>]

I've done a bit more to add some of the functionality of
emacspeak-table-ui into browsing org-mode tables. One can now read row
and column headers using, e.g. "ctrl-e b" for both (keystrokes
copied from emacspeak-table-ui).
One catch at the moment is that the command to move up through a
column requires a new function in org-table. I've asked for that to be
added but I include it here for people who can and wish to install it
locally.
A few things still to do on automated reading of headers but I already
find this useful.
cheers
Peter
