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 permission checks to custom fields
* adds permission checks to custom fieldsets
* adds separate permissions for custom fieldsets
* check for permissions in views
* Removes custom fieldsets from permissions config
* Proxy the authorization for custom fieldsets down to custom fields.
This allows us to use the existing permissions in use and have more semantically correct authorization checks for custom fieldsets.
* simplifies the authorization check for the custom fields overview
* removes special handling of custom fieldsets in base policy
I just realised that this code duplicates the logic from the custom fieldset policy.
Since we are checking for the authorization of custom fields anyway, we can just use the columnName for the fields.
* cleanup of unused imports
