Implement support for fuzzy pattern partials

[bmuenzenmeyer]

From the docs:

The shorthand syntax also allows for fuzzy matching on pattern names. This means that, if you feel your pattern name is going to be unique within a given pattern type, you can supply just the unique part of the pattern name and the partial will be included correctly. For example, using the shorthand syntax this partial could be written as:

{{> atoms-16x9 }}

• simple functionality
• simple unit test
• test using shipped source patterns
• lineage & reverse lineage
• remove todos
• re-add verbose partial support

---

• confirm if lineage works for stylemodifier patterns - looks like lineage_hunter might not be handling them
• update documentation on patternlab.io
