In some cases the 'size' field is not available resulting in some PHP errors such as:
```json
{"reqId":"03548fd9e3d3aca15a5796b3b35d7b9d","remoteAddr":"::1","app":"PHP","message":"Undefined index: size at \/Users\/lreschke\/Programming\/core\/lib\/private\/files\/fileinfo.php#125","level":3,"time":"2014-11-17T21:38:57+00:00"}
```
This can be experienced when creating a new empty file and deleting it right away, then when going to the trash bin this error is thrown.
- Reuse these methods on determineIcon()
- Generate permission string for the desktop client
- expose {http://owncloud.org/ns}permissions as additional WebDAV property containing the permission string
