Make Publishing Library Optional

[MicheleTobias]

Currently the Save feature only works if your library is set to "Publish Entire Library" in the privacy settings of your account. Let's figure out how to make this optional so people don't have to share their entire library. Note that we cannot change the Zotero settings, we can however change how Literature Mapper works within this framework. Can we save with Literature Mapper if the privacy setting for publish entire library is not checked?
