Add some mimetype

Patch by Glen Gray: Enable keepalive for Kasenna servers, they parse the User Agent string and check for _KA appended to the User Agent name.

Patch by Glen Gray: RTSP keep alive fix. If the server doesn't handle RTCP-RR packets and requires specific GET_PARAMETER commands (such as Kasenna) then the session times out when vlc is paused because the current version only sends the info when Demux() is called. Demux() is only called when data is received. This patch fixes this issue with a boolean that is set during PAUSED state that allows the timer thread to send the GET_PARAMTER messages instead and thus keeping the RTSP session alive.
