Title: UnixFileSystem Native Methods + Comprehensive FileOps test

I have implemented many native methods for UnixFileSystem, and have added tests for them and their corner cases into the `FileOps` test. This test passes in node and in the browser.

I have added a number of features to the in-browser node emulation that were required by these tests. Note that there are some known limitations to these new features. For example, permissions are not enforced, permissions on directories cannot be set, and you cannot move files that are present on the webserver. I hope to go back and fix these shortcomings at a later time.
