Cleanup: pass QString and QByteArray const-refs to qthelper functions

Passing of QStrings and QByteArrays was inconsistent in qthelper.cpp.
Unify to passing const-references. Passing by value is no big deal, since
QString and QByteArray do copy-on-write "optimization". Nevertheless, let's
keep it as consistent and effective as possible.
