Telephone-event format 97 support

Media server could not handle with Media Format:97 telephone-event.  When  
incoming  SDP Offer  contains  rtpmap:97  telephone-event/8000,   the replied 
SDP Answer doesn't contains this  Media Attribute type.   Then cause fail to 
detect DTMF on that call session.

To solve this issue
Yulian Oifa suggest  making the following change:
In 
https://code.google.com/p/sipme-media-server/source/browse/io/rtp/src/main/java/
ua/mobius/media/server/impl/rtp/sdp/RTPFormats.java#192
Change from
for (int i = 0; i < this.rtpFormats.size(); i++) {
    for (int j = 0; j < other.size(); j++) {

        if (this.rtpFormats.get(i).getFormat().matches(other.rtpFormats.get(j).getFormat())) {
                        if(this.rtpFormats.get(i).getFormat().getName().equals(AVProfile.telephoneEvent.getName()))                            
                                res.add(this.rtpFormats.get(i));                    
                        else if(!hasNonDtmf)
                        {
                                res.add(this.rtpFormats.get(i));
                                hasNonDtmf=true;
                        }
                }
    }
}

To:
for (int i = 0; i < this.rtpFormats.size(); i++) {
    if(this.rtpFormats.get(i).getFormat().getName().equals(AVProfile.telephoneEvent.getName()))                            
        res.add(this.rtpFormats.get(i));
    else if(!hasNonDtmf)
    {      
        for (int j = 0; j < other.size() && !hasNonDtmf; j++) {
            if (this.rtpFormats.get(i).getFormat().matches(other.rtpFormats.get(j).getFormat()))
                        {
                                res.add(this.rtpFormats.get(i));
                                hasNonDtmf=true;
                        }
                }
    }
}
