Add filters to the trade API

[JonRay15]

Request

Currently trades API only allows filtering by market, party, order, and datetime range.

We shoudl add filters for:

• [ ] buyer
• [ ] seller
• [ ] aggressor
• [ ] type

This would allow the Console to find closeout trades by filtering on TYPE_NETWORK_CLOSE_OUT_BAD and buyer = "network".

I added the other filters because while we're in here it makes sense to add these so we have more options in future.
