Allow customizable Origin header

[GoogleCodeExporter]

I would like to specify a custom Origin header in the request, instead of using 
the default "chrome-extension://blablabla" value all the time. This would be 
useful when testing with CORS-compliant servers that only allow a specific 
domain or list of domains.

What steps will reproduce the problem?
1. Create a POST request to a CORS-compliant service
2. Specify the desired Origin header in the headers list
3. Execute the request

What is the expected output? What do you see instead?
The provided Origin header is ignore and the default value 
"chrome-extension://blablablabla" is used instead.

On what operating system, browser and browser version?
Windows 7, Chrome latest

I believe This was not a duplicate. of #62. Is the User-Agent header related to 
CORS?
