Update and organize the Keywords table

[mbrubeck]

• Add two missing keywords, Self and proc
• Fix some mis-alphabetized keywords

For reference, my updated table exactly matches the keywords module from token.rs.

proc should have been removed as a keyword by now, I thought? And is Self actually a keyword?

[mbrubeck]

proc is still a reserved keyword. Self is a keyword:

fn main() {
    let Self = 1;
    let proc = 2;
}

<anon>:2:9: 2:13 error: expected identifier, found keyword `Self`
<anon>:2     let Self = 1;
                 ^~~~
<anon>:3:9: 3:13 error: `proc` is a reserved keyword
<anon>:3     let proc = 2;
                 ^~~~

I swear that we removed proc. Guess not.
