Pattern-categories-update

[knice]

What does this do/fix?

This begins to normalize block patterns and categories for service launch. Work in Progress, but it was requested by the Designs and Patterns group as an ongoing process.

This also fixes a PHP warning we saw with debug on. blocks.php was being included twice in functions.php.

QA

Tests

Does this have tests?

• [ ] Yes
• [X] No, this doesn't need tests because we'll be looking over categorization during and after service launch.
• [ ] No, I need help figuring out how to write the tests.
