Bug#749336: designer plugins libqwebview.so and libqquickwidget.so are installed to qttools5-examples

[Александр Волков <a.volkov@rusbitech.ru>]

Package: qttools-opensource-src
Version: 5.3.0-1

These plugins are not from examples and they should be accessible for 
designer and uitools module.
Maybe it'd better to create a separate package for them.
