[packman] Requires for devede

[Stephan Hemeier]

Can somebody add a requires for devede:
requires: python3-gobject-Gdk

Otherwise devede will not start:
devede_ng.py
Version: 4.16.0
Traceback (most recent call last):
  File "/usr/bin/devede_ng.py", line 48, in <module>
    mwindow = devedeng.project.devede_project()
  File "/usr/lib/python3.6/site-packages/devedeng/project.py", line 83, in __init__
    builder.connect_signals(self)
