This commit fixes two bugs:
- The camera position was never initialized until space was pressed. The camera position was therefore random
- Instead of saving the camera position, we actually want to save the delta camera position.

This commits merges the two orbit plane functions together in CTraffic.
The separation was necessary since XSwiftBus needed to be started manually
and until started, the pointer to CTraffic was invalid. Since XSwiftBus
is started automatically, it can be merged into one function again.
This commit also adds the feature to rotate the camera only if the space key
is pressed. This is equal to how FSX/P3D do it. Using the right mouse was
not possible, since X-Plane SDK does not offer that option.

Previously, the DBusconnection had to be set at construction time and could
not be changed over the DBusObject life time. Now a new connection can be
set anytime and as often as required.
The shared ownership is now also properly implemented by shared pointers.

* typo getRemoteAircraftsData -> getRemoteAircraftData (no "s")
* typo getEelevationAtPosition (double "Ee")
* get functions "const"
* added unit for some variables such as latitudeDeg
Instead of requesting it individually for each callsign and waiting for a
signal from xswiftbus, pass in a list of callsigns and use async callback
to read the data.
FSX/P3D have a nice feature to follow a remote aircraft with the camera.
X-Plane was missing this feature, since for X-Plane the remote aircrafts
are not known. However, from a plugin point of view, we know them and where
they are. So we can manually control the camera and provide a similar
feature.
This is still very simple. As soon as you move the mouse, the PoV angle will
change. In future updates, it should be change only while the right mouse
button is pressed.
QtDBus was the main component of xswiftbus' Qt dependency. This is the
first preparation step to get xswiftbus Qt free.
The new implementation is based on the low level libdbus library, which
was also in use by QtDBus itself. But instead of QtDBus, we use now a thin
C++ wrapper. To keep DBus handling async, libevent is used to monitor
timeouts and fds.
