Extract method to get cookie value

Browse Source 
Currently, trying to get a `csrftoken` from an empty cookie string will
crash the application. This creates a helper method to extract a cookie
value given a cookie name by pattern matching on the cookie string and
returning the value if one is found.

Fixes: #167
