[Dillo-dev] patch: the http header Content-Type half of charset conversion

Dug out my old patch and ripped out the meta tag stuff, the charset-setting dialog, etc. This much should be unobjectionable. Had good fun searching for things like dillo ??????? and seeing how many sites using windows-1251 or koi8-r worked now with this much of the code. Maybe half. Greek and Hebrew were somewhat less than half. And my fonts don't have enough coverage to make it fun trying Asian sites. Of course it doesn't matter much when everybody who participates here is a native speaker of some latin-1 language... Note that View Source will not show files as converted because the conversion is up in html.cc and View Source uses the cache.
