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
The reason for using float:left on inline-box is exactly because of the letter spacing. However it prevents you from changing the alignment (you can't center the boxes) and a non-floated parent's height wont adjust to contain its floated children, which could cause problems or too many extra divs in the future.
