PRD-3979: Fix issue with entering parameters in SUM and COUNT formulas
[PRD-3795] Parameter dialog does not allow to create multi-selection parameter without query.
Queryless parameters were formerly associated with PlainParameter objects, which only hold a single value.  Modified to use a StaticListParameter if .isMultiSelection().
Also needed to modify DataDefinitionFileWriter and ListParameterReadHandler, since there was a requirement that a <list-parameter> have a query.
[PRD-3795] Setting the strict values check to false for the StaticListBox for parameters without queries.
[PRD-3795] Additional test cases covering different parameter types.
