v2.5.8 - Event triggered in-app notifications support

• Add the feature: Event triggered in-app notifications support

Currently users have no control over when an in-app notification shows up. With this release users can now control when an in-app gets displayed based on an event that they track within their app. This "trigger" event is defined during message creation at www.mixpanel.com.

You can additionally filter the event based on properties that are tracked along with the event for even finer controls.
