Fix for SelectToolParameter rerun,workflow when multiple="true"

The following change allows multiple select values to be set on rerun and in workflows. I checked that DrillDownSelectToolParameter and ColumnListParameter stiil worked.

Need to override method to_html_value() from ToolParameter otherwise a list value will be returned as a string: "['a','b']" instead of a list: ['a','b'] and options will not be selected in method get_html_field() :
