[Fso] mdbus2 2.3.3 released, vala-dbus-binding-tool 0.4.0 released

[Dr. Michael Lauer]

Yeah, the canonical way is to export these values in the environment to
make mdbus2 (actually, any session bus client) jump onto the bus.

I don’t know of another/better way to query _the_ session bus address
for the current user (there might as well be dozens of it).

Thanks,
