Improve Messaging

[whimxiqal]

I never really liked most of the messages that are sent to the user for every-day type of stuff. Like "Searching..." is pretty bland, and I don't love the gold-orange color that's supposed to represent INFO statements. Also, "Success! Please follow the path" is pretty bad too, especially because sometimes the first move is a prompt like "type the following command", so "following the path" isn't even accurate.

A proposal should be made for

• a good, concise color scheme for messages,
• a list of concise wording for each of the known messages (also helpful for the eventual multi-language support),
• and a concrete system for when and where to use hover-text and title/subtitle messages.

Also, since we've married ourselves to Kyori Adventure, we should use it to its fullest extent.

Mostly addressed in v1.2, but can always be improved
