Internal data structures returned

[rvalle]

Internal data-structures are returned in some cases, for example:

For an open-gov referendum:

{"ayes":"0x0000000000000000004b41759f037253","nays":10000000000000,"support":"0x000000000000000000134c2f52751653"}

The reason is because we should be calling .toHuman() before returning, then the result would look like this:

{"ayes":"21,182,596,688,081,491","nays":"10,000,000,000,000","support":"5,431,790,688,081,491"}

which will be easier to parse.
