Keyboard shortcut to cycle creatures being scavenged by enemy

[elemanzer]

The scavenging notification system is a little broken. The mentor frequently fails to alert the user when a creature is being scavenged and the floating alert is easy to miss when other alerts are being repeatedly spammed.

Since there's already an ability to cycle angry creatures, it's strange not to have the same feature for this more critical event.

The proposition is that a keyboard binding like Alt+S should cycle each individual creature that is the active target of enemy scavenging.
