Title: tutorial: add note about mutability of vectors

(and fix trailing whitespace).

From conversation on IRC, it seems like the idea is that eventually [mut T] will go away, and you will instead declare things like `let mut v = [1,2,3]`, or `&mut [T*3]`. If this is the case, then it might be helpful to add a warning. Though if it is not coming for a long time, then maybe not.
