working indicator

Where is the indicator used?:
- on batch update.
- on every attempt to fetch a collection. To see it you would need to set bootstrapped data to false in /public/app/browseWorks.js : 146;
- while saving an edited work
I didn't mean that these should be inline-block, just that if necessary an inner div that's inline-block could be added. This seems like it would have unexpected consequences when changing the display mode under the feet of a lot of elements.
