Always write automated changes to skin metadata at the end of the file

Browse Source 
Apart from being cleaner (and allowing removal at the point of export,
if that is ever requires), this also gives us a better guarantee that
the metadata is going to take effect.

By writing the `[General]` section ourselves, we avoid any issues that
may be present from a user constructing the file (incorrectly)
themselves, such as multiple `Title:` entries or a malformed `[General]`
marker.

The main goal is to ensure that the name is updated to what we expect it
to be.
