Add user-agent header customization support to Visual Fizzler

[GoogleCodeExporter]

What new or enhanced feature are you proposing?

Allow VisualFizzler to customize the User-Agent header that it uses to 
download a resource when using the Import From Web option from the File 
menu.

What goal would this enhancement help you achieve?

Some web sites serve different content based on the User-Agent header and 
this means that Visual Fizzler may see different HTML than when using a 
browser. As a result, testing a CSS selector in Visual Fizzler may give 
different results when the same selector is applied in a different agent. 
By adding an option to customize the User-Agent header, Visual Fizzler can 
be configured to retrieve the same HTML an arbitrary browser version.

A concrete example of this issue can be observed when using Import from Web in 
Visual Fizzler to get the HTML behind http://www.microsoft.com. The attached 
file 
shows the response, which is an HTML page with a single paragraph reading:

"Your current User-Agent string appears to be from an automated process, if 
this is 
incorrect, please click this link: United States English Microsoft Homepage"
