better callback filtering for getMethodSigs

add a bool filter to getMethodSigs so it can also return script commands

example code reminder note:

//MainMenuGui.getPrototypeList();
//MainMenuGui.getPrototypeDef("onAdd");
function simObject::getPrototypeList(%this)
{
      %methodArray = %this.getMethodSigs();
      %methodCount = %methodArray.count();
      for (%i=0;%i<%methodCount;%i++)
      {
         %methodDef = getRecord(%methodArray.getValue(%i),0);
         %methodName = strreplace(%methodDef,"::"," ");
         %methodName = getWord(strreplace(%methodName,"("," "),2);
         warn(%methodName);
      }
}

function simObject::getPrototypeDef(%this, %funcName)
{
      %methodArray = %this.getMethodSigs();
      %methodCount = %methodArray.count();
      for (%i=0;%i<%methodCount;%i++)
      {
         %methodDef = %methodArray.getValue(%i);
         %methodName = strreplace(%methodDef,"::"," ");
         %methodName = getWord(strreplace(%methodName,"("," "),2);
         if (%funcName $= %methodName)
            warn(%methodDef);
      }
}
