Formatting.

• Use example as the module machine name throughout
• Remove note on deprecated/abandoned Drupal Console usage
• Remove reference to PHP 4 (!)
• Removed details on how to access routes without permissions: Added link to further reading on routing system and configuration
• Add a note on caching render arrays

@hansfn I think @kovalenkopavel is saying that an error is thown if the <code>use \Drupal\Core\Form\FormStateInterface;</code> statement is not included.

(I would suggest just moving the use statement to the form example code block below.)

The REQUEST_TIME constant is deprecated.
