Fixes #127

Update Request.php

See https://github.com/akalongman/php-telegram-bot/pull/228

Introduce Guzzle

Also rewrite entire command to require and API key from the config, as it is now required to fetch weather data.

Some structure.sql fixes

It's now possible to log all temporary PHP output to the debug log.

Use a single Guzzle Client instance to handle requests.
Improve debug logging mechanism.

1. Duplicate table `edited_message` removed
2. In MySQL 5.7 with default mode `STRICT_TRANS_TABLES` you can see error: `SQL Error 1101: BLOB/TEXT/GEOMETRY/JSON column '' can't have a default value`. To avoid this I removed all default values from TEXT columns.

Tested and works on MySQL 5.7.

Rename "methods" to "actions" for clarification.
Simplify the procedure of fetching the raw data input.

Adventures with Monolog, ready for the real world 👌

Check log file for correct contents.

Add test helper to modify static properties.
Move external log file test into main log test class.
