Hello,

Here is a proposal for new `org-forward-paragraph' and
`org-backward-paragraph' functions, currently bound to <C-DOWN> and
<C-UP>. Note that functions bound to M-{ and M-} are /not/
paragraph-related functions, but we might want to reconsider it at some
point.

In any case, the purpose of this rewrite is to mimic more closely
expected behaviour from `forward-paragraph' and `backward-paragraph'
functions, as found, e.g., in Text mode. Unlike Text mode, navigation in
Org mode is usually not linear, but both should feel the same, for
example, when the document is indeed linear.

These functions try to stop at interesting places, and skip mundane ones
(e.g., tables are treated as a single block) so navigation is still
fast.

I also added support for repeat argument.

WDYT? Also, what should be done with M-{ and M-}?

Regards,
