Doc: Fix occurrences of \Q_OBJECT in code snippets

'Q_OBJECT', even in a comment, interferes with automoc.
Prefixing it with a backslash solves the automoc issue,
but documentation looks wrong as content inside \code
is taken verbatim.

Move code snippets to doc/snippets and refer to them
with \snippet commands.
