Agent 2.18.1

Added The resource center (and its modules) can now be used with guide validation

Added Customers can now use the `annotateUrl` configuration option to provide their own function to determine what “page” a visitor is on. This is particularly useful for customer applications where the url never changes

Fixed Tooltips can no longer partially render off the top of the screen (making them unable to be dismissed)

Fixed Tooltips now wait to position until all their image blocks have loaded, preventing them from stuttering when rendered with large images

Fixed Images for guides created in the Visual Designer now always correctly get display: block, ensuring they don’t create a ~6px gap in their container

Fixed Tooltips are better at picking their render direction/offset, and have better handling for mobile-sized screens
