This update fix CVE-2018-10895 [0] and a few minor bugs.

[0] : Due to a CSRF vulnerability affecting the qute://settings page, it was possible for websites to modify qutebrowser settings. Via settings like editor.command, this possiblyallowed websites to execute arbitrary code.


This version fix compatibility issues with qtwebengine 5.11.x, add support for page printing, tab muting, third-party cookie blocking and has the web inspector β€˜enabled’ (does not require --enable-webengine-inspector) by default. It also ships a few bugfixes and changes.
