Improve file suggestions: Rank based on Last views

[mwitteveen]

Before saying anything I absolutely love Zed and I am pushing my developers at Anlytic.com to use it.

But... One major irritation is the suggestions when switching files.

The ranking is quite messed up. I have multiple files with the same name, but I end up so often in the wrong file when using the Search project files.

I really think this is very easily solved: Rank the searches: 1) files that are open 2) rank on last viewed 3) rank as you do now.

If that can be added the dev speed of switching files will increase SO much. I am now typing the folder name in front of my files. e.g. core/user.go or user/user.go or usergrp/user.go or meta/user.go or model/user.go

This is very annoying for filter.go or model.go files which I have around 30 packages.
