Subject: [PATCH] Add ifexgen_dbus command and required dependencies

l. ifexgen_dbus is a frontend / executable command, defined in the
package information (setup.py) and which calls the actual code.  I just
followed the same pattern as for ifexgen.

2. Rename D-Bus (correct spelling) to DBus (wrong spelling)
   because...python reasons :(
