Inconsistent address fields in ecocredit proto definitions

[ryanchristo]

Summary

Audit address field names and make sure we are using consistent names. For example:

• In MsgSell, MsgUpdateSellOrders, EventUpdateSellOrders, and EventSell we use owner
• In MsgCancelSellOrder, SellOrder we use seller

Problem Definition

Using different field names to reference the same address is confusing.

Proposal

• Update all instances of owner within the context of sell order to seller (or vice versa)
• Audit ecocredit proto definitions for address field names and make other changes if necessary
