Add strike syntax to wiki

[cmlenz]

Note that <strike> was already deprecated in HTML 4.01 and in XHTML is part of the legacy module. Other options would be to use a span with style text-decoration: line-through or the <del> tag which explicitly exists to markup "deleted" content in documents.

[cmlenz]

In case that wasn't clear, I'd prefer the <del> option.

Cap also pointed out on the list:

I like the idea, but this causes formatting problems on many of the default wiki pages, since they use -- as a long dash. I've seen both -- and used on other wikis for this, and seems more safe.
