Services of explorer can be a library

[oxarbitrage]

The services located at app/core can be reusable by other angular applications.

For example if i want to build an exchange with angular i can make use of the market services to get order book, trades, candles, etc.

To make it the services need to be cleaned(they are a mess) and isolated. Not a very easy job but doable and i think in the right direction.
