WIP: Upgrade develop to Laravel 6.6.1 (#7637)

I'm going ahead and merging this, since the upgrade doesn't break Flysystem any worse than the current develop is broken, so far as I can tell. 


* Upgraded framework to Laravel 6

### TO DO:

- Fix password restriction rules- the old library isn’t compatible with Laravel 6 :(
- Figure out why in-app API calls are returning “Unauthorized”

* More updates from Input:: to Request:: helper

* Switch to Request:: from Input

* Added passport config

* Fixed goofy password minimum in seeder

* Added laravel/helpers

* Changed ($item)  to ($item->id) in forms

I have no idea why this is necessary

* Changed ($item) to ($item->id) in forms

* Updated API middleware to auth:api

* Updated with added laravel auth.php values

* FIxed *&!^$%^&$^%!!!! ajax issue

* Switch to Request::get from Input::get

* Switched to Request facade

* Added password security minimums back in

The package we were using has not been updated to Laravel v6, so I created custom validators instead

* Added language strings for error messages for password rules

* Fixed `($item)` issue in formActions for partials
