Add Windows Support for tinker()

[fschirinzi]

I could make it work, that the app is opened in Windows. The only thing that doesn't work, for now, is that the variables are not populated.

I hope my pull request helps to bring this feature as fast as possible to Windows... because it's awesome!!!

Nice job, thank you! I'll take a look at the app implementation before merging this one :)

Hey, sorry that this hasn't been merged so far. Could you please update the PR so that it solves the merge conflicts and works with Laravel 7 too?

We will take care about this after this has been solved.

Unfortunately, I cannot make it to work.
