// IE version detection - http://stackoverflow.com/questions/4169160/javascript-ie-detection-why-not-use-simple-conditional-comments
// We need this as IE sometimes plays funny tricks with the contenteditable.
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}
// And to detect the version:
// ie === 6 // IE6
// ie > 7 // IE8, IE9, IE10 ...
// ie < 9 // Anything less than IE9
