[suggestion] - Reorganize Skript's packages

[Olyno]

Suggestion

After trying to work on Skript, i found it really annoying to have every expressions in the same dir. We can't find what we're looking for easily. That's why i'm suggesting to create some subpackages like "players" and move expressions related to the packages directly there.

Why?

I found the project was becoming a mess with all expressions, effects.... and new ones coming in the future.

In addition to this, I feel like a lot of simple property expressions could be registered directly without needing a separate class.

Something like PropertyExpression.registerSimpleProperty() that uses a default implementation could be used for that.
