Issue #79: FileWriter.seek() is broken in 0.9.5.

Browse Source 
The FileEntry.createWriter() method passes in a FileEntry object instead of a File object. As a result the FileWriter.length was not being set properly so when you do a writer.seek(writer.length) it would go to 0, so your next write would overwrite your file.

In order to fix this issue the FileEntry.createWriter() method now makes a call to FileEntry.file() to get the correct file size.  The File object is now passed to the FileWriter constructor.
