org/outshine speed commands consistency

[Hugo-Heagren]

I have noticed that there are a few inconsistencies between the default org and outshine speed commands:

Use	Org	Outshine
demote*	r	-
promote*	l	+
narrow subtree	s	r
mark subtree	@	m

There might be others I have missed.

* Admittedly, the analogy here is not perfect, since org uses org-metaright/left, which is not always a structure-editting command, but as far as quick keys as concerned I think this is a fair comparison.

i also behaves differently: in org it inserts a new heading after the current one (using a lambda specially for that purpose), and in outshine before.

For my own sanity (I use speed commands in both modes a lot, and often mix up the two) I was going to force consistency in my own config. Before I do though, I thought I would check if this is intentional? It might be nicer for many users if they were the same as far as possible. I would be happy to go through the lists and make a PR to bring the two together more if you like?

I don't use Outshine's speed commands myself, so I'd be glad for you to propose a PR to bring them in line with Org's. :)

Excellent! Will do.

I wrote a small mode outli which follows org speed keys closely. It's much simpler but does what I need.
