Initial Python3 support

Closes #1

See merge request !1

All default modules are now in Python3
Uses PySocks module for the actual Socks support.

One now can do DNS query over the proxy using
`resolve()` method.

```
t = torsockets.torsocket()
print(t.resolve("torproject.org"))
```

This commit also fixes a few typos in the torsocks.py file based
on the review feedback.

Python 3.3 doesn't work with the suppress module, which is included by
one our modules.

This fixes a Travis build issue.

Replace Atlas with Metrics link.

Update Cloudflare CAPTCHA signature, it looks like they started to
use `Cloudflare` instead of `CloudFlare`.

Update user agent header to match that of current stable Tor Browser.
Interestingly, I stopped getting CAPTCHAS after updating the UA string.

Add missing `Upgrade-Insecure-Requests` header.

Update `Accept-Encoding` header.

It looks like WikiLeaks' DNS servers no longer give you all IPv4 records
in a single DNS response, meaning that we end up with a lot of false
positives in a scan.  It's better to just get rid of the domain.

The KAU relay is no more, so let's use a pseudo fingerprint instead.

Executing the file is throwing an error "ValueError: Too many values to unpack".
This error is occurring because pyflakes is also returning the exact code where the error has occurred.

If we catch all exceptions inside get_relays_in_country(), we cannot
test the function properly.  In particular, we are unable to distinguish
Onionoo failure from the function's failure.  Handling the exceptions in
the calling function fixes this.

* Fixes pep8 violations and cleans up code

* Reverts some styling and updates

Reverts some fixes back to previous style
Changes the spacing of a new line before one comment
(#22)(#53)

* Catch exception in path selection

Occurs when the exit is not in the cached-consensus loaded from disk

* Fix exception where  os.makedirs(None) was called

This commit adds the command line options "-o" and "--logfile" that
enable logging to file.  This functionality required minor restructuring
that led to a simplification of the logging code.  In particular:

- We get rid of log.py because it was never really necessary.

- We use named loggers, so it's easier to figure out what module logged
  a given message.

- We rename our logging object from "logger" to "log" to make the code
  more readable.

- The restructuring means that we now also get to see Stem's logging
  messages.

This command line option hopefully makes it a little bit more difficult
for vigilant adversaries to discover our scanning activity.  It adds a
random value to the time delay between two subsequent circuit creations.
As a result, if an adversary monitors circuit creation timings, our
signal should be less periodic and thus less obvious.

We implement this feature by exposing a command line argument that
determines a random time delay in the interval [0, DELAY_NOISE).  This
delay is then either added to or subtracted from (both with probability
0.5) the given build delay.  By default, the argument is 0, and
therefore not in effect.

Travis CI discovered that PyPy in version 2.6.1 apparently lacks the
ENOTSUP variable.  This commit defines the variable if it does not exist
already.  The exact test error was:
