Added new functionality to undelete, including adding a button in the template. The Previous_status() function in models.py is having indentation issues, so it's not included yet
Adding in the models.py file but it DOES NOT work yet since there are indentation issues somewhere in the file.
Trying to fix an indentation bug.
Again, trying to fix indentation
Fixed a bug with indentation in the books model, also modified it so that finding the previous_status on a book would not return edited, deleted, or undeleted status
Reverting a change made earlier which ended up causing a bug where you could not edit multiple items at once
Merge branch 'undelete'
