The hyperlinks are not exported properly to DOCX, RTF and HTML format if the HTTP:// prefix is not added in the address when they were created.

Steps to reproduce:
1. Open RadRichTextBox and click on Insert tab -> Hyperlink
2. In address field type: www.telerik.com
3. Export the file to DOCX, RTF or HTML format
4. Open the exported file and click on the hyperlink
Observed result: The hyperlink is pointing to a local resource instead of opening the URL.

As a workaround, the regex used to match a partial hyperlink could be further extended. If this regex succeeds in matching a partial hyperlink the HTTP:// prefix will be automatically added to the partial hyperlink. Here is example of how the regex should be accessed:
(this.radRichTextBox.InsertHyperlinkDialog as RadInsertHyperlinkDialog).HyperlinkPattern
