[CM] new tar of cm-2.4.0

[Rick Taube]

ive put a new tarfile of 1.4.0 on ccrma that fixes a case-sensitivity bug in the rhythm function. 

ftp://ftp-ccrma.stanford.edu/pub/Lisp/cm/sources/cm-2.4.0.tar.gz


i also fixed the null typo bug in objects.scm that Ralf Mattes  reported and i reformatted intro.cm so that all the examples use lisp keywords in  'new' expressions. Hopefully the use of keywords will make the  syntax clearer for anyone  new to Lisp. Also, if you turn on  Syntax Highlighting in Xemacs you can get keywords displayed in their own color, which is even nicer. ( THere is also a color-coding utility in MCL that can be used for this sort of thing.)
