SDK Release Notes for 4.5 Server Release

Due to the limitation of documentation tooling that SDK releases must be tied to a Server release, new SDK releases are now included with the 4.5 documentation. This does have the advantage that SDK features that are dependant on a certain Server version (e.g. N1QL, Sub-Doc, FTS) are documented against the appropriate Server version, but has led to the Release Notes becoming fragmented and misleading.

Release Notes are vital to users/customers as well as internally to track updates to SDKs and any known/fixed issues. Without a canonical and rigorously maintained place to check these release notes, this is impossible.
