specifies a vlm configuration file to load when vlm is launched

Put all of the tracks in stream and media info - would like to make
this a chile under the disc category, but I don't see a mechanism for
that (yet).

To do - there still is a core dump that remains from before when CDDB
is disabled.

* modules/video_output/directx/events.c: fix to disable the screensaver in embedded mode when in fullscreen.

input: added INPUT_ADD_SLAVE to allow adding a slave input on the fly. (Don't use without a real reason).

* src/misc/vlm.c: partial revert of commit 9353. Do not use strncmp() when it isn't needed. It just makes the code less readable and more prone to bugs.

* fix bug in SDP parser

wx: really commit last commit

    - coding style fixes
    - adapted to new playlist API
    - only put generic things in Meta-information

wxWidgets:
    - Fixed playlist updating

core:
    - added playlist_ItemGetByInput
    - implemented input_item_t.b_fixed name : if this is set, the interface should not try to "improve" the display string.
