Removed Illuminate from components listing

While they are technically available as separate components, the level of coupling is so incredibly high that one is not usually usable without multiple others - with the only exception here being illuminate\database.

Until the others are packaged up in a way that makes them usable, with documentation on how to use them solo of Laravel, then these cannot realistically be considered as reusable components, regardless of anyones wishful thinking (my own included).
