Add support for search history
- Add `--history` option (e.g. fzf --history ~/.fzf.history)
- Add `--history-max` option for limiting the size of the file (default 1000)
- Add `previous-history` and `next-history` actions for `--bind`
- CTRL-P and CTRL-N are automatically remapped to these actions when
`--history` is used
Closes #249, #251
