 * Bugfix #230: Fix erroneous warnings about unsupported fsync

   Due to a regression in rest-server 0.12.0, it continuously printed `WARNING: \ 
fsync is not
   supported by the data storage. This can lead to data loss, if the system \ 
crashes or the storage is
   unexpectedly disconnected.` for systems that support fsync. We have fixed the \ 
warning.

 * Bugfix #238: API: Return empty array when listing empty folders

   Rest-server returned `null` when listing an empty folder. This has been \ 
changed to returning
   an empty array in accordance with the REST protocol specification. This \ 
change has no impact on
   restic users.

 * Enhancement #217: Log to stdout using the `--log -` option

   Logging to stdout was possible using `--log /dev/stdout`. However, when the \ 
rest server is run
   as a different user, for example, using

   `sudo -u restic rest-server [...] --log /dev/stdout`

   This did not work due to permission issues.

   For logging to stdout, the `--log` option now supports the special filename \ 
`-` which also
   works in these cases.
