[plt-scheme] Ann: log4scm v0.31

L.S.,

I've released 'log4scm' version 0.31, which
provides a logging facility for mzscheme.

Changes in this release:

2005-06-05:
        Added log-sync, which syncs the current log.
        Had to release the thread-cell stuff, because it caused
        problems with multiple threads. Some threads would not
        log anymore.
