Fixed the test failures on phantomjs and added a configuration option to let the user choose between getting an attachment as text or as a Blob, defaulting to text.

Stores documents and attachments, attachments accept and return Blob type.
Tests are run with mocks and if the URL containt /xwiki/bin/ then they are run on the live wiki
    (user must be logged in for them to pass).

jio.get({"_id": "a/b"});
changed to
jio.getAttachment({"_id": "a", "_attachment": "b"});

// Before:
jio.putAttachment({
  "id": "docid/attmtid",
  "data": "abc",
  "mimetype": "text/plain",
  "rev": "xxxx"
});

// Now:
jio.putAttachment({
  "_id": "docid/attmtid",
  "_data": "abc",
  "_mimetype": "text/plain",
  "_rev": "xxxxx"
});
