- Many times better performance. Before this, browser was spending all
  it's time garbage collecting or doing something. Now the bottleneck
  is in set fillStyle and fillRect which is probably where it should
  be.

- Refactor to pull off all the data received into RFB.d array and then
  process it. This allows a bit more flexibility in handling
  data that isn't sent in frame boundary packets.

- Properly ignore these server messages: SetColourMapEntries, Bell,
  ServerCutText.

- Hextile has an undocumented weirdness where RAW frames are often
  followed by a 0 byte that should be ignored.

- Coallesce client messages that are one after another. Without
  this the server seems to often ignore frames that are send right
  after another frame has been sent. This fixes a reconnect issue
  where setEncodings seems to be ignored. Also results in a huge
  performance increase after key strokes (by adding a update request
  to the key event message) because the server always sends an update
  instead of sometimes waiting for the next poll to be sent.

With hextile you can't know how many bytes are pending. So restructure
so that all the received data so far is passed to the processsing
routines.

- Prime number background worker that can be started, stopped and
  reset that calculates prime numbers and sends them back to the main
  page/thread.

- Semi-colon missing.

- Trim unused code in base64.js

- Most of the keyboard is now functional.

- host, port and password input boxes (populated by URL values).
- clear canvas on disconnect.
- Dotted border around VNC area.
- mirror bits for VNC password.

- DES encryption for VNC bit mirrors every bytes of the password. This
  commit has a hard-coded mirrored password. Need to ask user and bit
  mirror it.

- With image data across the wire it's Blue,Green,Red, so twiddle
  things around a bit.

Correctly handles all three mouse buttons and key presses on firefox
and Chrome.

Has a decent obj properties lister (dirObj).

- Requires wsproxy to proxy to the VNC server.

- wsproxy.py: creates a web sockets to TCP socket proxy.
- interact.html: prints received Web Sockets data and has text box to
  send strings.
