Ability to prevent photos from appearing in global search

[shivagowda]

Refer: http://www.flickr.com/services/api/upload.api.html

hidden=1 means keep the photo in global search results hidden=2 means hide photo from public searches

Provide ability to mention this setting here: https://github.com/richq/folders2flickr/blob/master/uploadr.ini#L16

Handle this setting here: https://github.com/richq/folders2flickr/blob/master/f2flickr/uploadr.py#L49 https://github.com/richq/folders2flickr/blob/master/f2flickr/uploadr.py#L353
