From 48939df9a5ef1ff20f4f9717d1341b51a50dff14 Mon Sep 17 00:00:00 2001
From: Ekdohibs <nathanael.courant@laposte.net>
Date: Mon, 4 Apr 2016 18:31:00 +0200
Subject: Escape more strings: formspecs, item descriptions, infotexts...

Also, change the escape character to the more standard \x1b
Thus, it can be used in the future for translation or colored text,
for example.
