Merged requested to merge el00ruobuob:Moneropedia_transaction_mixin into master
Created by: el00ruobuob
While reading moneropedia articles, i found that the Transaction article was still refering to a 'mixin_count' parameter.
I suggest to replace it with a link to @ring-size article, and adding the
faxt fact that it is not only the count of foreign transaction, but also yours all outputs.
