v1.3.0 - Visited blocks are now marked

During Brackeys Jam, I noticed some feedback related to how players marked valid blocks to understand the stage's rules.

Some players wrote down the blocks on paper, others in a notepad, etc. I finally received interesting feedback from a player who said it would be nice if the UI itself included a marker for valid blocks already visited.

Version 1.3.0 brings this feature, slightly modified. Valid blocks in a given stage order are not always valid when the stage is reordered, as some rules take the current block into account to consider the next one valid. Therefore, it wouldn't make much sense to keep the valid blocks listed after the character falls.

Now, valid blocks visited receive a slight color change, which can visually indicate the path already traveled in that stage. This gives players a better idea of the stage's rules.
