Subject: Implement support scripts for `tmux` and `dvtm`

This script adds two scripts that allows spawning a new window/pane in
`tmux` and `dvtm` in which `fzy` will be called.

Options data on the standard input are passed seamlessly, e.g.

$ find -type f | fzy-tmux
$ ag -g '' | fzy-dvtm -l $(tput lines)
