fzfrepl

[vapniks]

Hi @DanielFGray , fzrepl is fantastic, but I thought of several ways it could be improved:

• use the selections window for selecting lines of history or prestored lines
• keybindings for viewing the entire input or output
• keybindings for viewing the commands manpage or other help notes

I've made these changes (and more) in fzfrepl. Since it involved rewriting a large proportion of the code I've made it into a seperate project rather than issueing a pull request. Hope you don't mind too much.
