By setting the read deadline in streamReader.Read(), the deadline was
extended by the read timeout on each subsequent call. To avoid this, the
deadline is set in FCGIClient.Request(), before the first read occurs.

See #1094.

* Add Files action to template context. (#1198)

* Fixes to testFiles().

- Set os.ModePerm on directories created during test.
- Use filepath.Join() to create directory path.
- Use Fatalf, not Fatal.

* Make additional fixes to test cases.

* Fix test cases to use correct path format.

Dir.Open() in net/http requires '/'-separated paths while
filepath.Join() may produce paths with different separator.

* Remove directory created by test at end of loop.

* Close the FileSystem before returning.

* Initialize names slice to the number of entries.

Also, do not call os.RemoveAll() unless the path to the directory
is a valid one.
