Servebolt Optimizer v3.5.18

There was a small bug in the deployment of 3.5.17 where it offered the option to clear page caches by Tag/Category/Taxonomy Term when using Servebolt CDN. This is not possible with Servebolt CDN as it cache purges via the CacheTag HTML, thus purges the cache on every HTML page in one go.

The links and buttons that gave the extra unusable options have been removed.
