-fixed a bug in libdvdcss: the key wasn't searched when it had to.

dvdcss_seek : searches a new title key when
	-the flag is DVDCSS_SEEK_KEY,
	-the flag is DVDCSS_SEEK_MPEG, only if method is not "title".

dvdcss_seek with DVDCSS_SEEK_KEY flags does actually the same things as
dvdcss_title (which might eventually be removed).

Thus, the flag DVDCSS_SEEK_KEY (formerly DVDCSS_SEEK_INI) could not be
removed (sorry sam, I've mistaken you by forgetting that)
