use individual local gui_settings objects
Previously, we created a single gui_settings object (derived from
QSettings) and accessed it from the resource_manager object. That
design is not necessary and is not the way QSettings was designed to
be used. Instead of managing a single object, we should be using
individual QSettings objects where needed. Each individual QSettings
object manages thread-safe access to a single global collection of
settings. The Qt docs say that operations on QSettings are not thread
safe, but that means that you can't create a QSettings object in one
thread and use it in another without some locking. I'm not sure
whether we were doing that correctly, but with this change it no
longer matters. Each QSettings object does perform locking when
reading or writing the underlying global data.
