// Embed youtube videos in Blogspot comments by MS-potilas 2012 and YABTB
// See http://widgetgenerators.blogspot.com
//
// if oetag=0, just use video urls like:
//           http://www.youtube.com/watch?v=12345678901
//           surrounded by white space (video tag can be used, too)
// if oetag=1 (for nerdy blogs?), use syntax:
//           [video=http://www.youtube.com/watch?v=12345678901]
// config:
var oetag = 0;           // see above
var oetagname = "video"; // [video=zzz], maybe you like "embed" or "youtube" more?
var oelazy = -1; // -1 detect, 0 = normal, 1 = lazy (needs lazy load hack)
//
function oe_loadscript(filename) {
  var scr=document.createElement('script');
  scr.setAttribute("type","text/javascript");
  scr.setAttribute("src",filename);
