BUG FIX: Ball Dash can dash into the terrain, or through a pipe's borders.
There was a known "bug" where you can ball dash through the corner of a pipe to get inside it without using a proper opening, and also you can ball dash through a 'checkerboard' terrain pattern. This was kept in, as I thought it would make a fun exploit for speed runners (and I can always do the level design around this knowledge, so it wasn't too game breaking or something).
But recently someone found that you can also dash into a pipe from anywhere, AND also you can dash into the terrain (very bad, and definitely unintended ːsteammockingː).
So this patch fixes dashing into the terrain, and also fixes dashing through any pipe's borders. This unfortunately does mean the corner pipe exploit no longer works, but the corresponding 'checkerboard' terrain exploit still does. In the demo there was only one place this worked anyway, but in the full release I'll try to add a few spots where this can help speed runners.
