Re: DrumStaff vs Staff for instrument name

[Caagr98]

In `engraver-init.ly` (line 111 on my version), there is a line saying `\alias 
"Staff"`. That line makes the DrumStaff context listen to `\set Staff.*` as 
well as `\set DrumStaff.*`. (DrumVoice is similarly aliased to Voice.)

They're both equal, so I'd recommend using `Staff.*` for consistency. If there 
happen to be some properties that only exist in DrumStaff/Voice (such as 
drumStyleTable), I'd use them explicitly, but generally, I prefer the plain 
versions.
