Remove comment about race conditions when setting the selected device. Turns
out this wasn't at all the case. It was a signal loop, instead.

core/libparted.cpp to this new class and use this class in
PartitionManagerWidget
Move the libparted-specific code to inspect _one_ device to a static method in
LibParted.
Make scanning for devices asynchronous with the new DeviceScanner class.
Introduce a progress dialog to show progress while scanning.
Rename the progress dialog for applying operations to something less generic.
Remove the signal emitted when the status bar should change: It's the same
logic used for the signal emitted when operations change.
Remove the onFinished() method in PartitionManagerWidget and directly connect
the finished signal from the apply-progress-dialog to the scanDevices slot.
Rename the PartitionManagerWidget::selectionChanged() signal to the less generic
PartitionManagerWidget::selectedPartitionChanged().
Rename PartitionManagerWidget::clearSelection() to the less generic
PartitionManagerWidget::clearSelectedPartition().
NOTE: The DeviceScanner class is a thread and exposes some race conditions if
not used with caution (aka workarounds). See comments in
PartitionManagerWidget::onScanDevicesFinished().
