Added illustration of new standard VersionID Block using +k filetype modifier.
After we migrate to Streams, the //p4-sdp/<stream> depot paths become useful for identifying the p4-sdp major version, which is tied to the p4d major version. For example, the SDP r25.1 release will ship from the //p4-sdp/r25.1 release stream. This block will set the VersionID to for any given script to r25.1.<CL>, where CL is the latest changelist number to affect the given script.
Goals of this change:
* Enhance supportability by making it clear which release any given script version is released with.
* Provide clarity for the rare cases where customer is using an unreleased version, e.g. from a dev branch.
* Eliminate need for human manual bumping of the version number (via +k).
* Take full advantage of Streams structure.
