Don't add a "\n" after the textarea start tag rendering unless there's a 
leading blank line in a netui:textArea content.

         Key: BEEHIVE-1005
         URL: http://issues.apache.org/jira/browse/BEEHIVE-1005
     Project: Beehive
        Type: Bug
  Components: NetUI  
    Versions: V1Alpha, V1Beta, v1m1    
    Reporter: Carlin Rogers
 Assigned to: Krista Baker 
     Fix For: V1


When the netui:textarea contains blank line(s) in the beginning, the first 
blank line always gets removed.

I will attach a repro app.  
Repro Description:  Takes input from a text area and outputs it into another 
text area. If the first line from the input is a blank line then a carriage 
return is output after the textArea rendering and continue on with the text.  
The blank line should be included in the rendered text area.

Visual description:
Enter the following into the first textbox: "\nMyText" (where \n is a return or 
the input from the datasource)
Click Submit / Next Action
Expected output of the second textbox: 
<textArea>

MyText</textArea>

Actual output in the second textbox: 
<textArea>
MyText</textArea>

The reason is the first \n is used as the return after the textArea tag instead 
of including the \n at the end of the rendered text area start tag.
