  FS-7722 fixed issue with record_session including params when creating path

FS-7720 improve play_and_detect_speech to set current_application_response channel variable as follows:

    "USAGE ERROR": bad application arguments
    "GRAMMAR ERROR": speech recognizer failed to load grammar
    "ASR INIT ERROR": speech recognizer failed to allocate a session
    "ERROR": any other errors

  This is useful for determining that play_and_detect_speech failed because the recognizer is out of licenses
  giving the developer a chance to fall back to traditional DTMF menu navigation.

add images to spec file

FS-7656 fix various edge cases with video and non video files mixed into a source, fix a typo bug in file_read_video and fix same bug in mod_vlc, add a new flag to file_read_video to check if the handle is has active video, make mod_conference move the video in and out of a layer when the stream has video or not
