[Feature Request] Add a bonus level on most levels just like in regular SMB1

Title says it all.

This feature is planned, but it will be quite a while before I can get around to it. Currently, the plan is to add bonus areas accessible from pipes and vines sometime around v0.6, which is unfortunately still quite a ways off.

Before bonus areas can happen, underground and underwater levels still need proper exits to them. The current end stairs and flagpole pattern for these levels is actually just a place holder. Exit pipes will need to be used at the end of these levels instead.
