* livedotcom.cpp: 

    - improve a lot pts handling.
    - added --rtsp-caching.
    - implemented DEMUX_GET_TIME  and declared the input as seekable to
    make the interface displaying the time.
 Now I can read rtp stream from VLC using http export for sdp :) (MPEG4
video, MPEG 1/2 video and mp3 audio tested successfully)
