Issue: Meta-title controls

Currently, the meta title that VW uses is simply: pagename + sitename
This does not provide enough information in Google search results for users to click on. It does not match what people are searching for.

I believe this should be improved upon.
It would be very useful if we could define meta title per area.
And if we would have variables that we can use for the meta title. For example:
- article name
- site name
- category name

So we could do things like this:
Everything about {articleName}: a {categoryName} | {siteName}

Or basically anything we want to have in there.
