Vtrack and event endpoints

[danielguedesb]

Adds /event and /vtrack endpoints

Note: events_enabled column is added to accounts_account table:

SELECT uuid, price_granularity, events_enabled FROM accounts_account where uuid = $1 LIMIT 1

You can add the column to your postgres table by running the following command (adjust accordingly depending on your relational database):

ALTER TABLE account_accounts ADD COLUMN events_enabled BOOLEAN DEFAULT FALSE;

EDIT: Implements #1015

This is awesome! Thank you for tackling such a large feature implementation! My first round of feedback is largely centered around Go specific styling and use of the legacy (read: outdated) account code.

Just to verify, you're coding against this spec?

Yes, the implementation was based on PBS's Java version.
Thanks for the feedback!
