Midterm milestones status

Here's a summary of the project's current status

1. Make the OTR plugin register an encryption button in the tool (Pending, see bellow) and menu (Implemented) bars of the chat window

Current implementation adds a button in the tool bar which is dummy for the time being. I'm not sure what this button should do. For example it could be a toggle button (start/stop encryption) or it could bring up the whole OTR menu.

2. The above mentioned button should indicate the status of the current chat (Implemented)
3. The above mentioned button should also contain (at least) the following options

* Start an ecnrypted chat (Implemented)
* End encrypted chat (Implemented)
* Authenticate/Verify contact (Implemented)
* Auto encrypt every session with this contact (Pending. This can only be set globally in the configuration form for the time being.)
* Help/ What is this (Implemented)

4. Implement support for clients that do not have OTR (Implemented)
5. Add support for incoming fragmented messages (Pending, otr4j has to be extended)
6. Configuration intertface that allows generating and displaying our own key as well as managing other people’s keys (Pending)
7. JUnit tests that run with every protocol (Pending)
