ESF-ectomy: spinner
Removes use of spinner from elm-style-framework, replaces with use of the new progress indicator in elm-ui-widgets. Part of issue #357 (closed).
To use the new progress indicator, I had to define a color palette in src/Style/Theme.elm
. We can probably start using this color palette elsewhere in the app too.
How to Test
Launch a server, perform a server action (e.g. shelve), or delete a volume. Watch the spinner spin.
