Port install script to Powershell

[jupjohn]

Is your feature request related to a problem? Please describe.
The current install script is written in bash - preventing it from being run on most Windows-based machines without the use of git-bash/WSL.

Describe the solution you'd like
The install script should be ported to Powershell (as part of v3) for Windows installations.

Describe alternatives you've considered
-none

Additional context
Wanted an issue for tracking against the v3 "powershell script" milestone. Happy to take a dig at implementing it.

Won't be easy since powershell isn't as powerfull as bash.

This is very much not true. While personally I'm not a huge fan of PowerShell, everything that can be done using Bash, can also be done just as easily in PowerShell.

Ok..Maybe I should try to study it deeper.

You'll find that PS has a lot more power with .NET behind it. Everything done in the current bash install script can be done in PS just fine. I'll create a draft PR with the prototype if you'd like to see how it works.

Oh maybe that's the reason I felt powershell wasn't powerful enough. But do you need the .NET framework runtime to run .NET commands in powershell?

While I have to admit my days of writing extensions for Firefox date back to when chrome and XUL where still a thing: Why don't we create an actual extension to install things?

I've been using Bash for a long time, but I've rarely used PowerShell.
It will probably have to be made by trial and error. (Having a prototype would be of great help.)
I know that powershell, not cmd, has enough features, so it will be possible to implement.

There is one nice tool that was recently introduced.
I will move towards using ewen-lbh/ffcss, but it doesn't seem to support the upgrade process yet.
So, for the time being, a script will be needed, but since it seems likely that functions such as upgrade/GUI/autoconfig(userChromeJS) will be included, I am thinking of switching at any time.

With one unified manager, I can spend more time fixing bugs or developing features.

tldr; I will release powershell script in this version, but I have to go in the direction of using ffcss.

It's just not possible anymore. WebExtensions API is very limited (especially if compared to XUL) when it comes to editing the browser UI. See #47 .

Sigh Thanks.

Created #122 for implementation.

Experimental powershell script is merged.
