Objecten API

Omschrijving / Description

For the sake of completion and maybe tactical to fix them all together;
Currently 3 issues with the permission page:

1. Auth not set; UI Issue when creating a permission #374
2. Slow loading of permissions page; DH Taiga 596 (Should a github ticket be created?)
3. I want to be able to search for objectTypes; This ticket

In DH we already have quite some object Types. When I use the admin UI to add a permission i get a lengthily dropdown where I have to find the desired objectType in a seemingly random order.
Quick fix: At least sort them aphabetically
Actual request: make them searchable or something so that I can quickly find the desired permission.
Currently I am having cases where I have to add 10 permissions to an auth (for every environment) and have to aimlessly scroll through a huge list finding the type.

Bonus: Multiselect so I dont have to go through this screen multiple times, though this is less of an issue if all 3 previously mentioned issues are resolved.

Saving a lot of time and 'inconveniences'.
