Allows qTox to tell the difference between a default list that should be
upgraded when defaults are changed, ora user list that should never be changed.
Update docs to recommend using `%` operator with `QLatin1String` even for joining two strings (not only *more than two* strings).
Mentioned optimisation of "lightweight" QLatin1String copying-and-converting-to-utf16 when appending only works with QStringBuilder (operator %). Otherwise, QLatin1String will be converted to QString, and only then copied (appended), which is slower.
Add guides about using QStringLiteral, QLatin1String, QLatin1Char and QStringBuilder for more efficient strings.
Qt uses uses these techniques internally and can be considered as good coding practice when working with Qt libraries.
Update consists mostly of just moving things around and adding missing
section titles.

Changed highlight style of ~settings from italics to bold.
Removed obsolete remark about filter audio in A/V tab.
