Title: Header names are now case insensitive in format(...) and parse(...) methods.

I made the changes. I have added a case-insensitiveness test case in all the test files. Please review the changes.

If there is a better way to implement, please let me know. I will do.

For Ex., calls like,
headers.parse('content-type', val)
headers.format('accepT-encoDinG', val) are legal.
