In UserPathPanel variables aren't substituted

A variable definition for UserPathPanelVariable such as the following

<variables>
<variable name="UserPathPanelVariable" value="$

$

Kangas Sound Editor QI' appears as the initial value in the user path edit box.

The (workaround) fix I applied was to replace:

_pathSelectionPanel.setPath(idata.getVariable(pathVariableName));
at the end of method panelActivate in UserPathPanel.java with:

VariableSubstitutor vs = new VariableSubstitutor(idata.getVariables());
String expandedPath = vs.substitute(idata.getVariable(pathVariableName), null);
_pathSelectionPanel.setPath(expandedPath);

This has the desired effect of substituting variables in UserPathPanelVariable.
