What changes did you make?

Added the prefer-method-signature rule, which recommends to use foo(): void over foo: () => void.

It looks like these will be semantically equivalent in TS2.2. (And were in 2.0.) microsoft/TypeScript#13148 (comment)

How does this interact with member-ordering? I believe that rule treats these two different syntaxes differently w/r/t/ ordering.

I guess the fix wouldn't fully fix it in that case, because the method would then have to be manually re-ordered.
