vis: add non-default actions for vi compatible n/N motions

The following key mappings should result in the vi behavior:

 :map! normal n <vis-motion-search-repeat>
 :map! normal N <vis-motion-search-repeat-reverse>

The default remains unchanged, that is `n` (`N`) always searches towards
the end (start) of the file.

Fix #470
