Subject: Disable selection mode in text editors (#1141)

* Disable selection mode in text editors

Selection mode removes the space bar key (which is replaced by the Esc
key) and can be annoying in Emacs for example.
Text editor users probably have the `esc` key available.

* Refactor: Move EditorInfo related code to EditorConfig

Add the new EditorConfig class that handles configuration extracted from
the EditorInfo. It is accessible from the Config class for convenience.

This aims at reducing the length of already large classes and group the
code that was spread over several classes.---
