Apply modified SF patch 467580: ConfigParser.getboolean(): FALSE, TRUE.

    This patch allows ConfigParser.getboolean() to interpret TRUE,
    FALSE, YES, NO, ON and OFF instead just '0' and '1'.

    While just allowing '0' and '1' sounds more correct users often
    demand to use more descriptive directives in configuration
    files. Instead of forcing every programmer do brew his own
    solution a system should include the batteries for this.

[My modification to the patch is a slight rewording of the docstring
and use of lowercase instead of uppercase templates.  The code is
still case sensitive. GvR.]
