For get_news(), I'm using NEWS_MAX_LIMIT = 50 as a default query limit to prevent fetching too many news articles. no_total_limit can be used to suppress this.

It also acts as a page_limit to minimize api calls for the client if total_limit is more than 50. This mimics behaviour of the other endpoints like get_trades()

The difference is that the other endpoints don't have a default query limit... So get_trades('AAPL') would actually just fetch everything, 10000 data points at a time...

I wonder if I should add total_limit and no_total_limit to the other methods too, but it's a breaking change 🤔

@fumoboy007
Fix streaming news article event dispatching.
847829c 
News article events are different from other types of events (e.g. stock trades) because a single news article could be applicable to multiple symbols. For that reason, the streamed event does not have the usual `S` field that contains a single symbol; instead, the event has a `symbols` field that contains a list of symbols.

alpacahq#555 mistakenly assumes that the event has an `S` field. This commit changes the dispatching logic to instead use the `symbols` field.

(There is a similar [commit](alpacahq/alpaca-trade-api-csharp@be67b62) for the C# library.)
