feat(console): remove deprecated SPICE support in favor of noVNC

Browse source 
- Remove obsolete spice-html5 static assets and SPICE console templates
- Restrict default console types to VNC with migration 0012
- Filter out SPICE in VM creation form and backend capabilities
- Return friendly deprecation notice if legacy VM is opened with SPICE
- Clean up docs, architecture references, and libvirt-bootstrap scripts

## Description
WebVirtCloud is a virtualization web interface for administrators and users. It allows delegating virtual machines to users with role-based permissions. A built-in noVNC / SPICE console presents a full graphical interface to the guest domain. KVM is currently the supported hypervisor.

> Libvirt compute nodes listen on VNC/SPICE ports (`5900`–`65535`) to allow WebVirtCloud to proxy graphical consoles. Ensure your firewall (`ufw`, `firewalld`, or `iptables`) restricts these ports to accept connections **only** from the WebVirtCloud panel IP, and never exposes them directly to public networks.

* NOTE: The AT/MF keyboards can generate (via the 8042) two (MF: three)
* sets of scancodes. Set3 can only be generated by a MF keyboard.
* Set2 sends a makecode for keypress, and the same code prefixed by a
* F0 for keyrelease. This is a little bit ugly to handle. Thus we use
* here for X386 the PC/XT compatible Set1. This set uses 8bit scancodes.
* Bit 7 ist set if the key is released. The code E0 switches to a
* different meaning to add the new MF cursorkeys, while not breaking old
* applications. E1 is another special prefix. Since I assume that there
* will be further versions of PC/XT scancode compatible keyboards, we
* may be in trouble one day.
*
* IDEA: 1) Use Set2 on AT84 keyboards and translate it to MF Set3.
* 2) Use the keyboards native set and translate it to common keysyms.

/*----------------------------------------------------------------------------
** SpiceMainConn
** This is the master Javascript class for establishing and
** managing a connection to a Spice Server.
**
** Invocation: You must pass an object with properties as follows:
** uri (required) Uri of a WebSocket listener that is
** connected to a spice server.
** password (required) Password to send to the spice server
** message_id (optional) Identifier of an element in the DOM
** where SpiceConn will write messages.
** It will use classes spice-messages-x,
** where x is one of info, warning, or error.
** screen_id (optional) Identifier of an element in the DOM
** where SpiceConn will create any new
** client screens. This is the main UI.
** dump_id (optional) If given, an element to use for
** dumping every single image + canvas drawn.
** Sometimes useful for debugging.
** onerror (optional) If given, a function to receive async
** errors. Note that you should also catch
** errors for ones that occur inline
** onagent (optional) If given, a function to be called when
** a VD agent is connected; a good opportunity
** to request a resize
** onsuccess (optional) If given, a function to be called when the
** session is successfully connected
**
** Throws error if there are troubles. Requires a modern (by 2012 standards)
** browser, including WebSocket and WebSocket.binaryType == arraybuffer

/* Around version 45, Firefox started being very particular about the
time stamps put into the Opus stream. The time stamps from the Spice server are
somewhat irregular. They mostly arrive every 10 ms, but sometimes it is 11, or sometimes
with two time stamps the same in a row. The previous logic resulted in fuzzy and/or
distorted audio streams in Firefox in a row.
In theory, the sequence mode should be appropriate for us, but as of 09/27/2016,
I was unable to make sequence mode work with Firefox.
Thus, we end up with an inelegant hack. Essentially, we force every packet to have
a 10ms time delta, unless there is an obvious gap in time stream, in which case we
will resync.

Custom Browser ES Module Loader
===============================
This is a module loader using babel and the ES Module Loader polyfill.
It's based heavily on
https://github.com/ModuleLoader/browser-es-module-loader, but uses
WebWorkers to compile the modules in the background.
To generate, run `rollup -c` in this directory, and then run `browserify
src/babel-worker.js > dist/babel-worker.js`.
