Use `fc` instead of `history` to avoid `oh-my-zsh` alias

Feed all zsh history into fzf (not only most recent)

It turned out that Curses.can_change_color? returns false when $TERM is
set to screen-256color, which is perfectly capable of rendering 256
colors.

This commit adds --filter option so that fzf can be used as a simple unix
filter instead of being an interactive fuzzy finder.

To reproduce: `sleep 2; fzf` and press arrow keys

Add mouse support
