v0.7.0

Added

• The non-generic QueryOptions class can now be implicitly cast to QueryOptions<TArg, TResult>.
• New DataChanged event for queries, which is triggered whenever the Data property changes.

Changed

• BREAKING CHANGE: If a query succeeds and then fails on a refetch, query.Data now returns null/default, instead of the old data. Also, query.LastData now returns the data from the last successful request (even if the arg was different) instead of null/default.
• QueryOptions.OnSuccess is now called when a cached result is returned (unless it's stale). Note: EndpointOptions.OnSuccess is unchanged, and still won't be called when a cached result is returned.

Development

• More tests.
• Sample project improvements.
