Start an Off-the-Record implementation for Instantbird
A major shortcoming of our choice of Instantbird as the underlying messaging client for the new messaging bundle is the lack of Off-the-Record Messaging support. Tackling this issue breaks down into two parts: build an extension that binds to libotr to support the protocol (#10210 (closed)), and make the necessary graphical changes to Instantbird to empower the user (#10938 (closed)). We started on the former, producing the extension and making changes to Instantbird's internals to support the protocol. That concludes the part of this task that was supposed to happen in Q1/2014. Continuing this implementation is going to happen in Q2/2014.
