Rename QML singleton to Bobink and simplify singleton lifecycle

Replace QML_ELEMENT with QML_NAMED_ELEMENT(Bobink) so QML references
use `Bobink` instead of `BobinkClient`. Remove instance()/create()
factory in favor of inline s_instance set in the constructor. Import
BobinkPlugin statically in demo, link demo to BobinkQtOpcUaplugin,
and make library link dependencies PUBLIC. Add .qtcreator to gitignore.
