Feature request: Path history

[diamond-lizard]

It would be great if ag.el:

1 - remembered the paths the user searched (up to a customizable number of entries)

2 - made the default path in the next search be the previous one

3 - offered the user to select other paths in the history

4 - allowed (un)fuzzy search through path history

On my machine, the output of ag --version is: 2.0.0

My Emacs version is: 25.2
