Carbon: Add collections to be able to group saved snippets

[kievsash]

Expected Behavior

• [ ] 1. Saved snippets can be grouped to collections.
• [x] 2. Copy URL for specific snippet possibility so one can specify it in an article.
• [x] 3. Named snippets - one can specify name for the specific snippet
• [ ] 4. Search snippet by name

Actual Behavior

Saving snippet as one-level big collection with no grouping and search.

Thank you in advance!

These are all _great_ suggestions! Naming snippets is something we want to add first, and then search, but grouping them into folders is also a good idea!
