org-agenda.el: New commands `org-agenda-next/previous-item'.

* org-agenda.el (org-agenda-mode-map): Bind
`org-agenda-show-priority' to `C-c,' instead of `P'.
(org-agenda-next-item, org-agenda-previous-item): New
commands to move by one item down/up in the agenda.
(org-agenda-mode-map): Bind `org-agenda-next-item' and
`org-agenda-previous-item' to `N' and `P' respectively.

Thanks to Eric Abrahamsen for this idea and a first patch.
Let `org-agenda-time-grid' control if the grid is displayed.

* org-agenda.el (org-agenda-list): Ensure that the
list returned by `org-agenda-add-time-grid-maybe' is appended
to `rtnall' before checking if the latter is emtpy.

In the case where rtnall is empty (no item for current day), we do not
call org-agenda-add-time-grid-maybe.  This seems bogus because that
function is already computing whether the time grid must be included,
and does so according to the user's preferences.

In particular, the `org-agenda-time-grid' variable has a
'require-timed' parameter controlling the visibility of the time grid.

So, this patch :

 - removes the premature check for rtnall being empty,
 - inconditionally calls org-agenda-add-time-grid-maybe,
 - and finally checks the emptiness of the resulting list
   before pretty printing.
