Quality of Life improvements

Since I migrated Avoid Your Paste to my own framework BeetPx, I was motivated to do some adjustments to the codebase. Specifically, I added a quality of life improvement several people were asking about: indication of where Memories are located when “no memory” modes approaches its end.

So, the changes are:

• when a new Memory is about to appear, it is shown for a brief moment before, blinking, so it is more clear than it was before
• when the “no memories” mode (the pink one) is about to end, all Memories are drawn on top, greyed out, so you have a chance to quickly prevent an unexpected collision
