0.0.18

Note: APIs may be subject to change.

Changes:

• Document IDs and attachment names are now rejected if they could cause an unexpected Cloudant request. We have seen that some applications pass unsanitized document IDs to SDK functions (e.g. direct from user requests). In response to this we have updated many functions to reject obviously invalid paths. However, for complete safety applications must still validate that document IDs and attachment names match expected patterns.
• Updated dependencies.
