Strophe.ping.js was still in the no-dependencies build

Also clean up wrapper-end.js a bit as well as the grouping of dependencies in
non_amd.html

Remove locales from utils.js and include it in converse.js so that the locales
can more easily be removed from the build.

Also, remove build-no-locales-no-otr.js

This is now used in non_amd.html and means that the individual converse.js
modules don't need to support the non-AMD case.

Instead of using the deps-*.js files. Builds will currently break, they still
need to be reworked.

Also moved the refreshWebkit method to utils.

Plugins are now also updated so that they can get the closured converse object
directly and don't need to rely on _super.

change xmpp status also on icon-status click

Move the Occupants views and models to converse-muc.js as well as some
MUC-specific config variables.

Add synchronize_presence option

Fixes #596

Add a UMD header so that the example plugin can be used without require.js
Remove needles cruft and dependencies.

Fix non_amd.html

- converse-muc.js was overriding the global "converse" variable
  with undefind (the factory function didn't return anything)
- locales was not defined in utils.js in non AMD (not passed in
  the factory function)

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.

updates #576

This should keep diffs smaller and readable.
