Auto-Download GitStatusCache.exe

[dahlbyk]

A Chocolatey package largely makes this moot, but a potentially quicker intermediate step would be to simplify downloading GitStatusCache.exe from https://github.com/cmarcusreid/git-status-cache/releases/latest (https://developer.github.com/v3/repos/releases/#get-the-latest-release).

If Start-GitStatusCache notices the expected exe isn't found, I propose either:

1. Automatically download latest, or
2. Write a warning along the lines of "Could not find GitStatusCache.exe; call Get-GitStatusCacheExecutable to download."

If downloading latest also captured the release version, you could check for updates as well.

As you pointed out, install.ps1 already handles downloading so....let's call this an enhancement request to avoid hard-coding v1.0.0? 😊

I like it. The error message sucks if you didn't come in through an expected route.

Published #5 for this issue. I will leave open for a couple of days before merging in case there's additional feedback.
