Implemented timerange for mdplayer and use of it in widget Segment: if enable (option is use_timerange) when clicking a segment user can only read the video on current segment + adapted other widgets that need to detect segment to be able to use this option if it is enable so that segment detection is smoother + adjusted API testing form on iframetesting to use the correct api (form is still hidden by default)
// Resize anything
.resizable(@direction) {
resize: @direction; // Options: horizontal, vertical, both
overflow: auto; // Per CSS3 UI, `resize` only applies when `overflow` isn't `visible`
}
