CssEmbedControl throws exception in 4.1

Quick FYI in case anyone hits this.  When you use the CssEmbedControl in markup, it used to render if you omitted the MediaType property.  Since 4.1 it doesn't and you'll get:

StartIndex cannot be less than zero.
Parameter name: startIndex

[ArgumentOutOfRangeException: StartIndex cannot be less than zero.
Parameter name: startIndex]
   System.Text.StringBuilder.Remove(Int32 startIndex, Int32 length) +12613919
   Telerik.Sitefinity.Web.UI.PublicControls.CssEmbedControl.ConvertMediaTypeToString(MediaType mediaType) +430

Hi Michael,

Thank you for reporting this issue. It has been fixed in our internal build that will be released next week. I have updated your points.
