[#38] Ignore time references in code blocks

[YuriRomanowski]

Description

Problem: The bot should ignore time references in code blocks because they are most probably some logs or just some code quotations.

Solution: Ignore codeblocks by analyzing (undocumented) block structure of incoming Slack messages, using some simple code ignoring function when the block structure cannot be parsed.
