CovertAction_OverrideRiskStrings
Tracking Issue: #779
Allows listeners to override how risk chances are displayed in the covert actions screen (UICovertActions). The names of each risk and the texts displayed to represent the chance of each one occurring are passed in the event as two separate arrays of strings.
Note that the two arrays are in the same order, i.e. the first element of each array corresponds to the first risk, the second element to the second risk, and so on.
