macosx: work-around a playlist core limitation, which doesn't allow the UI to set the currently displayed root properly, so triggering a play can lead to unwanted results (close #7484)

- adjust detached time field margin to be as in main window
- set time slider to hidden by default in order to avoid small flashes on startup

Interestingly, the order inside the xib matters here...

Also shows possible warning for non native muxers.

It seems that the normal URLs included in the web page miss a
"signature" field and return 403 errors now. This approach has a number
of issues, it requires an extra HTTP request, still seems to fail due
to lack of signatures, and have different access restrictions than the
the web pages.

This shall meet the popular demand for now.

Fixing contrib 'make prebuilt' and 'make package' to use the repo version of change_prefix.sh instead of a version inside the contrib package.

The script shouldn't be included in the contrib package because the intention has not been to have different versions of the file depending on platform. If necessary the script can take into account differences between platforms instead of coming in different versions.

This resolves two issues with playback of RTSP-over-http streams from Foscam h.264 IP cameras.
Combined with a small fix to modules/demux/live55.cpp, VLC now plays 'rtsp://hostname/iphone/11?user:password&' from Foscam h.264 cameras.
