New Feature: Choosing post types to publish

Hello,

I don't know to use github very well, so I don't know if i did it correctly. 

I'm new at developing WordPress plugins, but i had an idea for Facebook plugin and tried to code. What do you think about choosing which post types are going to be published on a Facebook page? That's what i did. There are some details to implement yet (like default configuration). You can config it under Social Publisher Settings page. I think I haven't made enough tests yet, but i would like you to direct me on this. Did you like it or have any suggestion? Is it a good idea? I would like to know your opinion before finishing it. 

I would like to collaborate translating (I speak Brazilian Portuguese, by the way, can i translate it already?) and developing if possible.
Thanks
