Oekaki language encoding oopsie.

I just realized I still had some SJIS code in certain parts of the Oekaki – having all non-english support turned off in my browsers, I had forgotten all about removing the support code from the wrapper itself. No, you don’t need to install JIS support to draw on my doodle board. ;)

I’ll work on cleaning up the HTML it produces a bit more, fix a few more CSS thingies, then most likely remove a 1.2.1 revision o the CGIs shortly.
