3.0.0a2 dev (#1528)

# 3.0.0a2 / 2020-07-09

**General**

* Accept additional profile fields during registration (affiliation, website, country)
  * This does not add additional inputs. Themes or additional JavaScript can add the form inputs.

**Admin Panel**

* Redesign the challenge creation form to use a radio button with challenge type selection instead of a select input

**API**

* Admins can no longer ban themselves through `PATCH /api/v1/users/[user_id]`

**Themes**

* Spinner centering has been switched from a hard coded margin in CSS to flexbox CSS classes from Bootstrap

**Plugins**

* Revert plugin menu (`register_admin_plugin_menu_bar`, `register_user_page_menu_bar`) changes to 2.x code

**Miscellaneous**

* Fix issue with `Configs.ctf_name` returning incorrect value
* Add prerender step back into challenges.js
* Better handling of missing challenge types. Missing challenge types no longer bring down all other challenges.
