Now that csync builds as C++, this will avoid having to implement
functionalities needed by csync mandatorily in csync itself.
This library is built as part of libocsync and symbols exported
through it.
This requires a relicense of Utility as LGPL. All classes moved into
this library from src/libsync will need to be relicensed as well.
- I checked every occurence of a '%2' and make correct use of the
QString::arg overload that takes several argument instead of chaining
them, because the first argument can contains a '%1'
- I tried to look for every label that they either use plain text or richtext
and escape the user provided strings in there.
