Always import datetime no matter if dateutil is present

Handle experimental lookup method for bad domains Attempting to use NICClient with bad domains could hit a bad logical path that leads to an attempt to reference a variable that hasn't been defined. So in case we don't manage to find a nichost for a domain, just set `result` to `None`

committed support for new .org and .info format #60

[#59] Add support for dateutil.parser dayfirst and yearfirst arguments The WhoisEntry object should expose a dayfirst and yearfist argument to signify how the datetime format for the TLD should be parsed by dateutil. The base WhoisEntry class gives both those fields a value of False. Those are also the default values dateutil assumes.

Use timezone naive datetime objects Otherwise comparisons don't always work

Fix bad import in parser.py

Stylistic improvements on parser.py

Better date parsing support if python-dateutil is available The `strptime` and `strftime` functions can't deal with timezone names not known to the current system when there's a %Z in the format string.

Ensure lookups work with both unicode and bytes objects

Add .рф TLD expiration_date regex
