**This commit removes Base64 (and Flash) support** This commit converts websock.js to used Typed Arrays for the receive queue (and tweaks rfb.js to ensure that it continues to function, since only Firefox implements `%TypedArray%.prototype.slice`). Base64 support was removed to simplify code paths, and pave the way for using Typed Arrays for the send queue as well. This provides two advantages: first, we allocate a buffer ahead of time, meaning the browser doesn't have to do any work dynamically increasing the receive queue size. Secondly, we are now able to pass around Typed Array Views (e.g. `Uint8Array`), which are lightweight, and don't involve copying. The downside is that we initially allocate more memory -- we currently start out with 4 MiB, and then automatically double when it looks like the amount unused is getting to small. The commit also explicitly adds a check to the compacting logic that avoids calling the copy functions if `_rQlen === _rQi`.
