Connect to a SignalR server from react-native

#react-native-signalr

Connect to your SignalR-server with a active websocket-connection from react-native.
Supports all error-handling and reconnection, including longpolling if needed.

Today the module shims the jQuery-dependency that signalr has.
There is however an ongoing task upstream to remove this dependency.

PS. Does NOT pull in the entire jQuery-library. Only shimes the few methods SignalR needs.
Tested on iOS and Android. No known issues.

#Install:
```
npm i react-native-signalr --save
```
