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
* adds select2 placeholders to select lists
To allow us to clear the selection on „select2“ selects, we need a placeholder attribute
See: https://select2.org/placeholders
* Removes empty option from multiple select
select2 requires an empty option value on singular selects, but not on multiple selects.
When selecting multiple options, this empty option would be shown as selectable otherwise, not clearing the selection.
* Adds the option to clear select2 instances
Sets the correct options to allow clearing of out select2 instances. The empty placeholder is required, since clearing only works when a placeholder ist set (event an empty one).
See: https://select2.org/placeholders
* Removes the „Clear selection“ option from select lists
Since we can clear the select2 lists with their native clearing method, we can remove this hack
* Updates generated assets (css/js)
