228c81171c fix an edge case where "ab =" wasn't throwing an error 
Input like "ab =" should result in an error because it's a variable definition
with no content.

e0d11b1ec2 include source context EVERYWHERE 
This provides filename/line/column context for any error I could possibly find.
To achieve this, I made it so that all ScoreUpdates have source context, so when
updating the score results in an error, we can print out the line and column
number corresponding to the error.

It's a bit more complicated than that, because score updates are nestable (e.g.
event sequences can contain cram expressions can contain chords, etc.), which
essentially gives us a stacktrace whenever a score update results in an error. I
punted on giving the user the full stacktrace, in favor of doing something
simpler and just showing the bottom-most error, because that's probably going to
be the line and column number that's the most helpful.

709d669d9c improvements to line/column information in scan/parse error messages 
1. Added column to parse error messages.

2. It turns out that we weren't even keeping track of the line and column where
   a token starts, let alone including it in the error message. Added
   `startLine` and `startColumn` fields to the scanner struct, made it so that
   they get updated in sync with the `start` (i.e. start index) field, and made
   it so that we're using the start line and column in error messages, instead
   of the _current_ line and column, which was less helpful.

3588fd4689 make PitchIdentifier an interface instead of implicitly using certain fields of Note in certain situations 
In accordance with the "don't make invalid data representable" principle.

This also allows us to create a LispPitch type in alda.lisp, which will just
wrap PitchIdentifier.

67e6931abe consider "slur" to be an attribute of note only, not duration
