Bug#862452: Update to newer QtWebKit

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Package: libqt5webkit5
Version: 5.7.1+dfsg-1
Severity: wishlist

QtWebKit has recently restarted, due to it being faster,
lighter and more standard compliant than the Blink-derived
QtWebEngine, see e.g.

http://qtwebkit.blogspot.it/2016/08/qtwebkit-im-back.html

for the announcement (and comparisons). A “Technology
Preview” compatible with Qt 5.8 is available

https://github.com/annulen/webkit/releases/tag/qtwebkit-tp5

Would it be possible to package it (as `libqt5webkit-ng5`
for example) when Qt gets upgraded? It might also be possible
to package the previous Tech Preview 3 

https://github.com/annulen/webkit/releases/tag/qtwebkit-tp3

for Qt 5.7.

The upgrade would give better HTML5 support to browsers
relying on this engine, such as the Otter browser, as shown
in the Otter issue about MathML support:
