Prevent whitespace from passing honeypot checks

[anthonymfowler15]

Description

When a honeypot field is filled with a newline ("\n"), protect_from_spam does not properly block the request. This is because "\n".blank? returns true.

Related Issue

#47

Motivation and Context

As described in the description, this change will make protect_from_spam more robust and block requests where there are any values in the honeypot fields.

Perhaps this could be simplified to the one string value we allow:

Suggested change

	head :ok if honeypot_fields.any? { |f,l| !params[f].blank? || params[f].to_s.length > 0 }
	head :ok if honeypot_fields.any? { |f, _| params[f].to_s != "" }
