v0.6.0

Breaking:

• Only saves to persistent storage on browser close. This should be a notable speed improvement, but is potentially breaking if you were relying on the storage value to always be up to date. (#105)

New:

• Variable editor now has a linting and typeahead engine based on the current query (#101).
• Write multiple queries in the editor and run one at a time (#106).
• Simple search in Documentation Explorer (#86).
• Supports a fetcher that returns Observable, which enables experimentation with subscriptions in GraphiQL (#104).

Fixes:

• More resilient to errors during introspection, better support for servers that do not support subscriptions (#79).
• Ensures a scrollbar doesn't appear if not needed on some Linux browsers (#91)
• Polished CSS a little bit.
