Renamed general reader script to `wallr`, indicating wallabag as the
underlying reader input.
Fixed listing of unread articles which showed read articles before.
Added shortcuts to sxhkd's academia mode:
the existing `r` invokes wallr with unread article display;
newly added `shift+r` invokes wallr with all articles displayed.
Added script to easily read wallabag articles on the command line (or
open them in browser), using the wallabag-cli python program in the
background.
Once invoked, will fetch a list of articles (optionally restricted to
read/unread/starred), and allow a choice through fzf.
Will then display the article in the user's preferred pager, editor, or
browser.
Can be invoked through the shell via `reader`, or through sxhkd shortcut
`r` from 'academia' mode (`alt + a`).
