[w3m-dev 03129] Re: X-Face

* configure (use_xface): ask
* fm.h (_Buffer): add header_source
* buffer.c (reshapeBuffer): fix reshape when reading stdin with image
		fix disappearing header when reading stdin
* file.c (xface2xbm): check file existence
* file.c (readHeader): save to tmp file
		X-Face when activeImage & displayImage
* main.c (dispI): comment out checking content type
* main.c (stopI): ditto
* scripts/xface2xbm.in: update compface URL
		read from file $XF
		write to file $XBM
