			* We replace `mLastUsedUnicodeDirectory` and its manual memory management with
  a `UniquePtr` named `sLastUsedUnicodeDirectory`
* We remove `AutoRestoreWorkingPath`, as it never was actually necessary and
  was left in, "just in case."
* We remove the timeout stuff, as that never actually worked, at least with
  the current implementation of the file picker; perhaps it worked with the
  legacy file picker APIs, but it doesn't work with the Vista+, COM-based stuff.
* We also get rid of `IFileDialogEvents`, as all of that stuff was needed for
  timeouts. It also adds additional complexity that impairs our ability to
  implement out-of-process file pickers in a future bug.
* We replace `do_CreateInstance("@mozilla.org/file/local;1")` with
  `NS_NewLocalFile`.
* We add `HRESULT` error handling to all of the method invocations on COM
  interfaces.
* We replace `CLSCTX_INPROC` with `CLSCTX_INPROC_SERVER` in `CoCreateInstance`
  calls.
* We remove `CoInitialize` and `CoUninitialize` calls. Those have been
  unnecessary ever since we added `mscom::ProcessRuntime` instantiation during
  startup.
* We add a missing check for private browsing mode in
  `nsFilePicker::RememberLastUsedDirectory`.
