Update inline comments for hook.php and getUpdatesCLI.php

Make sure that logging is set directly after Telegram object initialisation. (thanks @jacklul for pointing this out)
Proofread and update utils.md file.

 ## Logging
-Telegram bot library feats [Monolog](https://github.com/Seldaek/monolog) to store logs.
+PHP Telegram Bot library features [Monolog](https://github.com/Seldaek/monolog) to store logs.
 
-Logs are divided in those streams:

 ### Debug

 ### Raw data
-Incoming updates (json string from webhook and getUpdates) can be logged in a text file. Set this option with the methods:
+Incoming updates (JSON string from Webhook and getUpdates) get logged in a text file:

-Why I need raw log?  
-Telegram api changes continuously and often happen that db schema is not uptodate with new entities/features. So can happen that your table schema would not be able to store valuable new information coming from Telegram.

+Telegram API changes continuously and it often happens that the database schema is not up to date with new entities/features. So it can happen that your table schema doesn't allow storing new valuable information coming from Telegram.
 
-If you store raw data you can port all updates on the newest table schema just using [this script](../utils/importFromLog.php).
-Remember always backup first!!
