pager: add "save link", "save source"; change & document some keybindings

* `s{Enter}' now saves link, and `sS' saves source.
* Changed ;, +, @ to g0, g$, gc so that it's somewhat consistent with
  vim (and won't conflict with ; for "repeat jump to char")
* Changed (, ) to -, + so that it doesn't conflict with vi's
  "previous/next sentence" (once we have it...)
* Add previously missing keybindings to about:chawan
