Move partials in views/static to views/application

I think this is the more canonical place for stuff like this these days!
It's nice to be able to just say the short name when calling `render`.

Here's the answer I looked up about it: https://stackoverflow.com/a/9892081/107415

My immediate motivation is that I'm looking at creating more About
pages, and thinking about where to put them; I think maybe we trash the
`StaticController`, move these partials out to here, and move terms
into a new `AboutController`?
