Update Project/Package Title

[olabrahmi]

you really need to change the name from 'banner' to 'header', i think yo udon't know the difference XD you just wasted 5 mins of my life installing this, for it in the end to not be a banner, like the name says.... disappointing

Interestingly phrased, but I agree. That said, I'm not using or maintaining this anymore (see #23). I'm also not sure if there's a better package name available on npm but you (or someone else) could take a look and make a suggestion.
