v0.6.1: Fix error in XHR downloads and allow synchronous FS in AsyncM…

…irror.

Turns off assertions in our calls to writeUint8 in our XHR code, since we expect to pass large values that the code clamps to 8 bits.

Also removes a restriction on AsyncMirror; now, synchronous file systems can be async mirrored. This is useful if you want to prevent synchronous XHR.
