short validator
Description
Field Validator that checks if the short specified is within a certain range.
Parameters
- fieldName- The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required.
- min- the minimum value (if none is specified, it will not be checked).
- max- the maximum value (if none is specified, it will not be checked).
- parse- if set to true, minExpression and maxExpression will be evaluated to find min/max.
- minExpression- expression to calculate the minimum value (if none is specified, it will not be checked).
- maxExpression- expression to calculate the maximum value (if none is specified, it will not be checked).
You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using 
expression can be slightly slower, see the example below.
Warning: do not use
${minExpression}and${maxExpression}as an expression as this will turn into infinitive loop!
Examples

    <!-- Plain Validator Syntax -->
    <validator type="short">
        <param name="fieldName">age</param>
        <param name="min">20</param>
        <param name="max">50</param>
        <message>Age needs to be between ${min} and ${max}</message>
    </validator>
 
    <!-- Field Validator Syntax -->
    <field name="age">
        <field-validator type="short">
            <param name="min">20</param>

    <!-- Field Validator Syntax with expression -->
    <field name="age">
        <field-validator type="short">
            <param name="minExpression">${minValue}</param> <!-- will be evaluated as: Short getMinValue() -->
            <param name="maxExpression">${maxValue}</param> <!-- will be evaluated as: Short getMaxValue() -->
            <message>Age needs to be between ${min} and ${max}</message>
