This new iteration of select-kit focuses on following best principales and disallowing mutations inside select-kit components. A best effort has been made to avoid breaking changes, however if you content was a flat array, eg: ["foo", "bar"] You will need to set valueProperty=null and nameProperty=null on the component.
Also almost every component should have an `onChange` handler now to decide what to do with the updated data. **select-kit will not mutate your data by itself anymore**
This commit will for example allow this:
```
api.addDiscoveryQueryParam("my_param", { persist: true });
```
If you page is forum.foo.bar/?my_param=1, when clicking on an "unread" link for example this query string will be kept.
When there is a topic draft in place instead of showing "+ New Topic"
we will show "+ Open Draft", this allows topic drafts to be much less
intrusive.
Also, fixes draft handling of tags
