Fix distcheck

Use _PYTHON for python modules, so they're byte compiled, and install
them in pkglibdir, not pkgdatadir.
Add missing files to POTFILES.in
Improve window layout

Enable use_layout_size in GtkClutterEmbed, so the window is correctly sized
to include the entirety of contents, and use a homogeneous grid for forecasts.
Make sure the forecasts are spaced enough

Ensure that at least 6 hours separate consecutive forecasts, to avoid
multiple elements for the same apparent time (as we don't show the actual
time but just the part of the day)

the new gjs Package framework on a real application.
