Simple qt test app

This is a simplistic qt test application, that downloads a chromium snapshot
(~76MB). Works fine on native linux, works fine with patched Qt5Network.dll,
fails to complete the download with unpatched Qt5Network.dll (missing several
MB). Thus it's reasier to reproduce and doesn't need Origin at all.

Observable: The 1byte reads from the socket result in data bursts from the
system's buffer. Not quite sure if the system buffer or the application buffer
overflows, but it seems there's too much data from the peer and too slow qt
application data handling, thus there's some data lost.

For Origin this probably means failing checksum/size checks for the download
and thus erroring out.
