QmlInspector: Some code cleanups

* Inlined empty method implementations
* Removed unused QDeclarativeViewInspectorPrivate::cursosPos
* Small simplification in setting shortcuts
* Prefer const & for QList parameter

(cherry picked from commit df1835f06c99d95a6f35ab84abc5fa7950cb5fe7 in
Qt 5 / QtDeclarative, to make synchronizing future changes easier)
