Update of /cvsroot/mantisbt/mantisbt/core
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv2968/core

Modified Files:
        custom_field_api.php custom_function_api.php 
Log Message:
Support for custom values for dynamically generated possible values.  This can 
be done by setting the possible values field of the custom field to 
"=<custom_func>" rather than "fixed_a|fixed_b|fixed_c".  There are two 
implemented examples, "=versions_enum" and "=categories_enum".  See 
core/custom_function_api.php.
