Title: prefixed $sep  global in title override method

Ideally the `$sep` global variable could be a property of `WPSEO_Frontend`.

Since the `wpseo_replace_vars` function uses this global to it and I didn't want to make huge changes I just prefixed the global var for now to prevent naming collisions.

`$sep` became `$wpseo_title_separator`
