Bolt2 small fixes

 * Fixed styling for Edit User page
 * Added Omnisearch permission
 * Added Profile function (+ some styling fixes), might want to copypasta Backend stuff for #789 ?

**Note:** Need to add two new permissions in a current `permissions.yml` when updating from an older Bolt version:
```
profile: [ everyone ]
omnisearch: [ everyone ]
```

Still, Omnisearch needs to only show results that are allowed according permissions.
