Remove disclaimer

This is just true of all of Rust, and doesn't make a lot of sense now.
Especially as we move towards finalizing things, I think it's time for

-Rust is a work in progress. The language continues to evolve as the design
-shifts and is fleshed out in working code. Certain parts work, certain parts do
-not, certain parts will be removed or changed.

-This manual is a snapshot written in the present tense. All features described
-exist in working code unless otherwise noted, but some are quite primitive or
-remain to be further modified by planned work. Some may be temporary. It is a
-*draft*, and we ask that you not take anything you read here as final.
-
-If you have suggestions to make, please try to focus them on *reductions* to
-the language: possible features that can be combined or omitted. We aim to keep
-the size and complexity of the language under control.

-> Formalizing the grammar accepted by the Rust parser is ongoing work, but

-> Preliminary versions of this automation exist, but are not yet complete.
