Subject: [PATCH] Remove '---' from firstLineMatch

There is no need for it. It is actually a hindrance rather than help because it gobbles up a possible way for YAML sub languages (like Ansible playbooks) to override language-yaml grammar choice. For example they `language-ansible` could use `--- # ansible` or similar but this is not possible because language-yaml matches *everything* using the document separator on first line. Also I can think of at least one other file type that starts with "---" by convention (Jekyll .md templates) so starting with '---' is not very YAML specific.
