* input/input.c, libvlc.h: implemented new way to break vlc preferences :

 start-time and stop-time (both given in second) ;)
 
 Becarefull that it won't work with all files because of missing/wrong
 media length (ex: ts, broken avi, ...) or the fact that the headers
 will not be read (ex: mpeg1 ps, perhaps ogg, ...)
