App-relative filesystem api

It would be nice to able to do things like:

...
upload: function (req,res) {
  _.each(req.files,function(file) {
    File.create({
      filename: file.filename,
      extension: file.extension,
      mime: file.mime
    }).success(function(fileModel) {
      file.save({
        path: '/public/files',
        name: file.id + "." + file.extension
      });
    });
  });
  res.json({success:true});
}
...

Instead of having to use __dirpath and then navigate back upwards to the appropriate place. Might also make sense to create the specified directory if it doesn't exist.

For now, you can use config.appPath:

...
upload: function (req,res) {
  _.each(req.files,function(file) {
    File.create({
      filename: file.filename,
      extension: file.extension,
      mime: file.mime
    }).success(function(fileModel) {
      file.save({
        path: config.appPath+ '/public/files',
        name: file.id + "." + file.extension
      });
    });
  });
  res.json({success:true});
}
...
