World select suggestions

[weluvgoatz]

The world select should list the level count and percentage complete underneath the name of the world, just like in #2040. If we want to skip cutscenes in the world's level count, level dots should have an option to be counted, and cutscene level dots can be checked to not be counted.

My other suggestion is that after the first cutscene or so, the player is informed of the existence of the world select since many people do not know about it. This also could work if we use tooltips in certain situations, like this.
