For keys, QSettings escapes all characters outside of [-a-zA-Z0-9_.]
by using percent encoding, and changes '/' to '\'. That is,
settings.setValue("qt.*", true)
will be written to an .ini file as
qt.%2A=true
This means that QSettings can not be used to write general-purpose
qtlogging.ini files. Fix this by applying the reverse transformation
method from QSettings when reading in the .ini file.
[ChangeLog][Logging] Qt will now accept qtlogging.ini files
written by QSettings.
