* Audiotest: Add a primitive interface

This allows the user to specify a played file / stream. Useful for Audiolib
debugging and development.

* Audiotest: Add SSL support for HTTP streams

* Client/Playlist.cpp: Remove SSL config definition

Well, this just isn't a Qt class on Windows for some reason.  This might
or might not break SSL functionality while downloading remote URLs over HTTPS,
but we do not seem to support streamed audio in the mainline game yet, only in
Audiotest, so we do not need to worry about it that much anyways, yet.

* Audiotest: remove SSL from Windows builds

Fine.
