Might fix PIC linking issues on amd64

You need to escape (with \):
* quotes that are part of a file's name or option's value
* backslashes

    this allows the persistable properties to be fully loaded before initialization and allow
    for control to initialize faster in design mode. AUTOLOOP property now works properly
persistpropbag.cpp, vlccontrol.h: decoupled volume property from VLC so that value can be used
    without having VLC initialized
test.html: added volume control

* fixed the copying of the re-worked http-interface to our release bundle. (not really clean, but I don't know how to do this in a better way...)

* vlm fix. change "input :foo=bar :foo2=bar2" into vlm compatible option handling
* mosaic fix. always enable transcode when using an sout chain

I really don't like the Sort menu and Services discovery menu code. If
someone has a better idea feal free to change it.

  Seems to work for WM RTSP. No support yet for Kasenna,
  since I don't have proper access to one at this moment.
