- Separate FileMount into separate FileMount and WritableFileMount classes. This separates the (relatively simple) read-only code from the (soon to be even more complex) read/write code. It also allows you to create read-only mounts which don't bother with filesystem accounting, which is nice. - Make openForWrite/openForAppend always return a SeekableFileHandle. Appendable files still cannot be seeked within, but that check is now done on the FS side. - Refactor the various mount tests to live in test contract interfaces, allowing us to reuse them between mounts. - Clean up our error handling a little better. (Most) file-specific code has been moved to FileMount, and ArchiveMount-derived classes now throw correct path-localised exceptions.
