Added a line on how to start the web interface

Straight from the bikeshedding dept.

* Avoid setting `tor_details` globally as this could be called when the
  config file has not yet been parsed and therefore it may not respect
  `advanced-tor_binary`

* Fix Microsoft Azure meek endpoint, format

* Update default meek tor bridges

Based on the tor Launcher preferences (default bridges):
https://gitweb.torproject.org/builders/tor-browser-bundle.git/tree/Bundle-Data/PTConfigs/bridge_prefs.js

* Fix active meek tor bridges

* Add support for testing via http when the site is https

* Clarify scope of `--no-http` settings

this is a bit subtle, but if any error happens in _setup_complete
itself, the errback only sees it if it is added *after* the callback

This is aimed at reducing fingerprintabiliy of ooniprobe
Fixes: https://github.com/TheTorProject/ooni-probe/issues/480

* txtorcon>=0.19.0 dropped support for twisted<15.0.0

related to #751

* Regenerate manpages
* Bump version number
* Add changelog entry

* Use the same logic for encoding header values and keys as measurement-kit

* Fix edge case that lead us to not do stripping of response headers
 when response body was null.

* Bump all the tests version that depend on httpt test template

This will allow us to distinguish when the fix for the body length is
rolled out

* Add the most basic telegram reachability test

* Add measurement list filter for telegram

* Add Telegram test to the IM test deck

* Add checks for also doing HTTP requests

* This is useful to ensure that even if there is a TLS or HTTP MITM we
  are more sure that we are actually speaking to a telegram server as
  opposed to the MITM

* Add support for testing Telegram Web

* Smear load generated by scheduler, see #630

It runs ASAP after the installation. It survives reboot in predictable
way: avoids double-run and does not skip scheduler cycle on restart.
It supports non-24/7 operations as it targets running @daily task within
2.4 hours window, so the probe that was down will likely run a task
on boot and boot time is random enough for load smearing purposes.

* Schedule decks right after initialisation, see #630

That's required as refresh_deck_list() does not schedule anything if the
`config` is not `is_initialized()`.

Another possible way to implement this behavior is to postpone
RefreshDeckList.task run checking config.is_initialized() in
should_run().

* Add support for generating summary results for more tests

It's now possible to see from the measurement list if the following
tests presents anomalies:
* http_header_field_manipulation
* http_invalid_request_line
* facebook_messenger
* whatsapp
* vanilla_tor

* Add .DS_Store to gitignore

* Improve debug level output
