Issue #1313980 by Albert Volkman, Lars Toomre, jn2, xjm, jhodgdon: Clean up API docs for Node module

Roll-back of node titles as fields. The Entity Translation module in
contrib can add this back, but for everyone else it creates a *huge* WTF.
Apologies for how late this is coming, but better now than post-alpha. :\

- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.
