Wrap font style plugin in Angular directive

@settinghead 
I don't see any two-way data binding logic here. This will not work because it only binds _once_ when the component is initialized, but will not put further updates in the UI onto the scope. Please take a look at an example here:
https://github.com/Rise-Vision/widget-settings-ui-components/blob/master/src/_angular/color-picker/dtv-color-picker.js

Essentially, you'll need to put variable on the scope and bind them to parents (line 5), watch any variable changes on scope and feed them back onto your jQuery based component (Line 13-25), and finally react on "collectAdditionalParams" event in case the settings UI controller initiates a variable collection action (we have to do this because there's no two-way data binding in jQuery. A pure Angular component will not need this part).

Thanks and please let me know if you have any questions.
