Social media integration for all social media

[Lunarequest]

@matsuyoshi30 I figured out how to do the social media on the TOML end of things so now we have a simple slot in for all social media.

[[params.social]]
    name="social media"
    url="url to social media"
    icon="icon"

adding this how many ever time you want for each social media. I have tested it. It works pretty well. I hope this is enough to close #27.

@advaithm Looks great to me. Thanks! I'll add and check this feature to the example site.
