defaults: do :filetype stuff unless explicitly "off"

Browse Source 
Until now, the default `:filetype ...` setup was skipped if the user
config touched `:filetype` in any way (including implicitly via `:syntax
on`).  No one needs that, and it's very confusing.

Instead, proceed with `:filetype ... on` unless the user explicitly
called `:filetype ... off`.
