Document rogue's "Auto" rotation

[jdelvare]

Is your feature request related to a problem? Please describe.
When the rotation is set to "Auto" for my combat rogue, I have no idea what type of rotation is being done by the simulator. I also can't remove Expose Armor from the rotation.

Describe the solution you'd like
When Rotation is set to "Auto", I would like to see a text describing how the simulator is behaving. Is it picking one of the APL saved rotations? If so, which one? If not, what are the rotation rules for "Auto"?
Additionally, I think it would make sense to at least let the user choose a rotation with or without Expose Armor (for example with a checkbox).

Describe alternatives you've considered
Maybe rotation "Auto" can be removed and "APL" becomes the only supported rotation type?

Additional context
When looking for detailed simulation results this morning, I noticed Expose Armor in the list of abilities used, even though I did not ask for it. I couldn't find a way to disable it when rotation is set to "Auto".
