Add a viewing option menu that would include:
- View All Files
- View As A Folder

"View All Files" allows the ability to determine amongst other things what file(s) are causing the compressed file to be much larger then expected

My use case is that I have created my own backup script for ~/ using tar and bz2 which has a number of excludes for things I don't need/want backed up but every so often a exceedingly large file sneaks in like when a new app is installed and the only way I have to determine what that file is is to use File-Roller and then sort on size 

Reproducible: Always
