200alpha3

[Matthew Flatt <mflatt@cs.utah.edu>]

The exp-tagged code in CVS for MzScheme and MrEd is now 200alpha3.

The changes are minor to most users:

 * Added a 'pref-file option for `find-system-path', and
   `get-preference' and `put-preferences' functions to MzLib's
   "file.ss"

 * MrEd now access global configuration (e.g., default font settings,
   or whether to outline inactive selections) through the preferences
   file, instead of through resources.

 * MrEd's `get-resource' and `write-resource' are deprecated; use
   `get-preference' and `put-preferences' instead.

 * Syntax objects for `lambda', `case-lambda', etc. expressions can
   supply an 'inferred-name property to set (or override) the resulting
   function's inferred name.
