Problem/Motivation
If you go to the Field List page (admin/reports/fields) you will see that the USED IN column don't have the bundles labels in alphabetical order, so sometimes is a little difficult to find an information if we have a field shared between many bundles.
Proposed resolution
Sort the USED IN column using the sort() function.
Remaining tasks
User interface changes
The USED IN column will have the bundle labels in an alphabetical order.
API changes
None.
Data model changes
None.
