add random resource also for auto_login

The ChatBox.show() method was being called for every invocation, 100ms after
the fact, instead of it being called only once.

Fixed that and also changed to call it at the start.

OTR messages which are setting up an encrypted session.

The OTR functionality is now fully decoupled and can be removed entirely
without breakage.

Also fixed errors with converse obj not being defined in the MUC plugin.

First component to remove is MUC which was moved to src/converse-muc.js
The components are written as plugins and use converse.js's plugin machinery.

Update the plugin docs somewhat with new insites found while working on the muc
plugin.

logout if you are using auto_login=true

Don't steal focus when chatbox is opened automatically

- Adding a new parameter "focus" to ChatBoxView.show
- Removing the parameter "callback" not used

Keep scroll position on minimize/maximize

The default mockup is now a "live mockup" in the sense that it renders based
upon the templates in `src/templates`.

We use Jasmine and the test_utils to render the different elements.

This should keep diffs smaller and readable.

Fix for issue #261

When converse is first initialized this.model.get('closed') is undefined, at least with some configurations. This patch initializes the attribute with !show_controlbox_by_default if it is undefined.
