SanitizePathJoin protects against directory traversal attacks by
checking for requests whose URL path look like they are trying to
request something other than a local file, and returns the root
directory in those cases.
The method is also careful to ensure that requests which contain a
trailing slash include a trailing slash in the returned value. However,
for requests that contain only a slash (requests for the root path), the
IsLocal check returns early before the matching trailing slash is
re-added.
This change updates SanitizePathJoin to only perform the
filepath.IsLocal check if the cleaned request URL path is non-empty.
---
This change also updates the existing SanitizePathJoin tests to use
filepath.FromSlash rather than filepath.Join. This makes the expected
value a little easier to read, but also has the advantage of not being
processed by filepath.Clean like filepath.Join is. This means that the
exact expect value will be compared, not the result of first cleaning
it.

Before this change, a read of size (let's say) < 10, into a buffer of size 10, will return EOF because we're using CopyN to limit to the size of the buffer. That resulted in the body being read from later, which should only happen if it couldn't fit in the buffer.
With this change, the body is properly NOT set when it can all fit in the buffer.

* Added plaintext support to file_server browser
This commit is twofold: First it adds a new optional
field, `return_type`, to `browser` for setting the
default format of the returned index (html, json or plaintext).
This is used when the `Accept` header is set to `/*`.
Second, it adds a preliminary `text/plain`
support to the `file_server` browser that
returns a text representation of the file
system, when an `Accept: text/plain` header
is present, with the behavior discussed above.
* Added more details and better formatting to plaintext browser
* Replaced returnType conditions with a switch statement
* Simplify
