Change default value of autoConnect & autoReconnect option

[usirin]

I am finding myself to write new Kite({url: '...', autoConnect: false, autoReconnect: false}) all the time in following scenarios:

• writing unit tests for kite
• if i am initializing other objects other than kite as well, i want to have a preparation phase and want to call kite.connect() afterwards.
• if i want to have a kite as a singleton e.g export default new Kite({ ... })

Having to write auto{Connect,Reconnect} all the time is a little bit tedious.

I would probably not need autoReconnect, since it's about connecting after disconnecting. But i still would expect from an object to connect something when i tell it to.

@gokmen I think this is good enough to be one of our breaking changes for moving forward to v2.
