Bug#940849: Upgrade the package to 1.9.3

[Bernhard Übelacker]

Dear Maintainer,
I guess this has to do with the package libgtkd-3-0.

Currently testing contains the version 3.8.5-1+b2.
That one got compiled with ldc 1:1.17.0-2.

The version 3.8.5-1 got compiled with ldc 1:1.12.0-1.
Installing that version from [1] makes tilix at least
run and open its window.
That might be another workaround, until tilix 1.9.3-1
transitions to testing.

This situation might be a side effect of the rebuilt +b2
of tilix 1.8.9-1 failing against ldc 1:1.17.0-2.
That was taken care of by uploading tilix 1.9.3-1,
that currently waits for gtk-d to transition and
the armhf build before it transitions to testing.

Kind regards,
Bernhard
