We no longer use Gitter for development talk and similar. So we might
want to remove it?
This patch removes Gitter from README, help page and features page. And
replaces it in the help modal with POEditor, our translation platform.

As an active part of the community prefers Matrix.org over Gitter, we
should link Matrix.org as a place to meet us.
As the matrix and gitter channels are interconnected. We don't loose any
message if a person decides to go for one or another.
We use an more universal way of translation to make it easier to provide
a link to various platforms.
