Error Handling on Reconnect

[JessyCat92]

Actual behaviour:
If you connect to a channel you can handle connection error with the promise handling .catch()
But if you set reconnect = true then this will only work for first try of connection.
For reconnects there is no error handling. So it results in "(node:20312) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 18): Unable to connect."
The reson is simply, that tmi.js has no error handling here (it calls simply this.connect() with out catching the error from returned promise)

Expected behaviour:
There should be any kind of error handling. Maybe via eventhandler "error" or maybe a new "reconnect error"

Error log:
"(node:20312) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 18): Unable to connect."

tmi.js is only supported by Node 4.x at this time. There is no ETA when we will support Node 6.x and 7.x
