[Governance] Token Factory

[mktcode]

The token factory should inherit from the OctobayStorage, so that only the latest version of the Octobay main contract can use it. This is also where oracle checks are performed, so the token factory really only needs a single function (createToken(string _name, string _symbol)) where it uses the token template (#4) to launch new tokens.

Also appropriate events must be emitted so that we can index newly created tokens in our subgraph.
