Make JsEngine::Evaluate() return a wrapper for v8::Value to accessdifferent variable types easily

This shouldn't be necessary, since there's a GetProperty that accepts an int,
right?

       {
         case AdblockPlus::Filter::TYPE_BLOCKING:
           type = "blocking";
           break;
         case AdblockPlus::Filter::TYPE_EXCEPTION:
           type = "exception";
           break;
         case AdblockPlus::Filter::TYPE_ELEMHIDE:
           type = "elemhide";
           break;
