No way to force a cache clear if metadata is changed

[capeterson]

e.g. if a new object is created after the global describe is fetched the record details tab won't work with it as it's not in the cache.

Proposal: clear the global describe is an unknown recordId prefix is found, and add a button to clear the metadata cache for the current connection to the UI.

In v1.5 Grey Tab now clears the cache for an org when an expired/invalid SID is encountered. Partway there.
