* Cleanup
* API tests for asset models and related cleanup/improvements
* Api license test. Tests incomplete because create/update/destroy are not implemented yet in the controller
* API Category tests.
* Manufacturers API Test.
* Implement License Create/Update/Delete Methods for API and enable test.
* Add missing gate for api. Fixes only superadmins being able to generate Personal Access Toekns
* Fix some n+1 problems
* Use route in notification dropdown to make sure we link to correct page
* Work on better UI support for checkout to non-user. Fix links on index bootstrap table, work towards eliminating assignedUser
* Remove Asset::assigneduser() relationship. Instead add a checkedOutToUser() method and/or port to using assignedTo()
* Adjust string to fit new reality
* Fix#3780. Move the consumables getDataView method to the ApiController. Not entirely RESTful, but it's a weird method that probably doesn't need its own controller and the functionality would be strange to stack on the userscontroller...
* Fix file uploads to assets and restore the delete route.
* Add asset maintence edit action to index.
* Suppliers asset list should link to the related asset, not to the supplier with same ID.
* Asset models page should use polymorphic formatter on assigned to to better handle assorted item types.
* Comment out more assigneduser fallacy until we figure out the query builder approach to searching for location text.
