Allow getExtensionSettings to accept event as parameter

[PrateekTikku]

Description

The function turbine.getExtensionSettings() can potentially be called from inside any condition/action exposed from an extension. Hence, the extension configuration should also be able to use the rule's synthetic event using %event%

#157

Motivation and Context

Passing the rule's synthetic event as parameter to turbine.getExtensionSettings() function call must be possible as this function internally calls replaceTokens() which replaces tokens with actual values. If in the extension configuration the user has used %event% as token, the turbine.getExtensionSettings() call from inside the action's/condition's module should be able to pass the event parameter it possess, so that the tokens are replaced with actual values coming from the event.
