Bump to 1.4.1.

Documentation improvements for 1.4.0.

v1.3.0

* XHRFS with synchronous listings download is now deprecated. Will be removed next major version (2.0).
* Made BFS amenable to API documentation. We now have API documenation. :)
* Added XHRFS static method to construct asynchronously from listings URL.

1.2.1: Fixes rename in Emscripten environment.

Previously, we were not appropriately updating the Node object for renamed files,
causing certain Emscripten-compiled programs to fail.

Make it a larger version bump, as it adds IsoFS.

Preparing for a release.

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.
