Added max/min font sizes not showing up for cloud widget

Apparently, the problem was that this._settings wasn't defined because of a scoping issue when using the constructValue method. When the check "if (this._settings != "undefined")" was added to the code, that solved the undefined bug but it also prevented the maxFontSize and minFontSize code from running. Now, the code runs. (I tested multiple times locally to make sure that I didn't break anything else.) 

Would appreciate this being pulled in! Thanks!
