Autotest Kickstart

[erickmoura]

It will be nice to have automatic testing for our code.
XChange already has its own testing features. Probably you can find some inspiration there.

The idea is to make sure our higher logic works - like collecting data (tickers, order book, balances etc) and successfully dispatching data through firehose.

At some point I will add some continuous integration to GitHub, so automatic deploy and tests run for new PR's.
