Closes#3402, Closes#3428
-------------------
### Components
- Added GhostSelectComponent to handle async select creation (h/t @rwjblue)
- Added GhostRolesSelector (extends GhostSelect) for displaying user role options
- Created StoreInjector for surgically inserting the store into things that normally wouldn't have them.
### Users Settings
- InviteNewUserModal now uses GhostRolesSelector & defaults to Author
- The role dropdown for user settings has permissions set per 3402
### User Model
- Added `role` property as an interface to getting and setting `roles`
- Refactored anything that set `roles` to set `role`
- isAdmin, isAuthor, isOwner and isEditor are all keyed off of `role` now
### Tests
- Added functional tests for Settings.Users
- updated settings.users and settings.users.user screens
- fix spacing on screens
### Server Fixtures
- Fixed owner fixture's roles
When a using the forgottenRoute if you enter an incorrectly formatted
email address you would see the error message 'Invalid Email', however
if you entered an email address that was correctly formatted but missing
the error message would be 'Invalid email address'.
This fixes the discrepancy.
closes#3426
- added transfer ownership endpoint
- added owner to roles.permissible
- manually removed owner from roles.browse
- removed hard coded author role
- fixed tests that were passing due to hard coded author role
- added testUtils.setup(‚roles‘)
Closes#3291
- Adds redirects based on roles as defined in the case
- Adds new mixin `CurrentUserSettings`
- For authors, all settings pages redirect to `users/self`
- For editors, all settings pages other than specific users redirect to `users`. Any user that is not self or an author redirects to `users`
- New _shame.scss to hold styles/components which need to be refactored or removed
- layout.scss and floatingheader.scss merged into global.scss/shame.scss
No Issue
- Move authentication related handlers to the Application route.
- Switch Sign Out from a button to a link. Use the signout route
to handle invalidating the session and redirecting instead of
an action from a button.
- Clear error messages on signin page when pressing log in button.
- Errors are now always shown on sign in screen and a success
notification is shown after sign out.
- Update functional tests.
