[Qt-interest] Change default background color for search results (QPlainTextEdit)

[Jaco Naude]

I had the same problem. I have to say that its probably not the best
solution, but I keep a list of highlighted words and remove their formatting
before doing a new search. However this gets slow when you type and the
document is big. I know there must be a better way since Creator does
something similar much faster.
