Warning: Don't update QtWebkit libs Options

[vader]

I installed webcat a while ago - it is a good second browser running webkit rather than gecko. It can plug holes when gecko doesn't render correctly. The author suggests updating to QtWebkit 5.212, which he has created. I tried these on the Gemini and they are a no-go. I didn't poke around extensively, but they just display a blank page. Luckily I followed the instructions and kept a copy of the old libraries, so I am back to normal. This is just a warning for other curious sailors thinking of updating QtWebkit. If you don't keep a backup, you might find it difficult to revert. I have one if anyone gets in that state.
