Emoticons re-activated

Some articles, especially the old and transferred ones, had some 'cryptic' content like 'icon _ wink' (without spaces) in the text. Well, that were some placeholders to provide icons on the position. Meanwhile I added those content filters to the current blog system and hopefully you should get nice emoticons instead of stupid text placeholders in my articles. 😁.

Feedback on missing content translation for icons would be very helpful! Thanks for patience and your efforts in advance.
