v1.5.0

Rules improvements and fixes:

• Added forbid: non-empty option to the 'braces' rule
• Added forbid: non-empty option to the 'brackets' rule
• Fixed the rule 'quoted-strings' for explicit octal recognition
• Fixed the 'line_length' rule to skip all hash signs starting comment

Fixed some code smells.

Now the library uses ServiceLoader to load rule classes instead of Reflections.

Updated the dependencies to the latest versions.
