Fix parse_http_time and add tests

Browse Source 
* It seems parse_http_time wasn't parsing correctly any date with commas (RFCs
  1123 and 850). Fix that.
* It seems parse_http_time was reporting the wrong month (they start at 0, not
  1). Fix that.
* Add some tests for parse_http_time, covering all three formats.
