Add initial internal version page

We kept urls in examples to point to company website.
However this site is heavy to load and moreover it changes
overtime leaving example screenshots obsolete.

Introduce internal qt version web ui page which will
be default page for examples and which displays basic
information and can work offline.

For start show version info and command line options
for chrome://qt
