default mappings

[aloispichler]

The default mappings are
s for <Plug>(leap-forward-to) and
S for <Plug>(leap-backward-to).
To me, this is not natural and counterintuitive, because the g motions (gg and G) are opposite: lowercase goes up, uppercase down. So, I suggest to change this behavior (but this is only my opinion).

s/S is consistent with //?, n/N, and f/F.
