Changes log for v2.1.f (UnderDev) profile

The following changes were made for v2.1.f on GitHub (released 29-MAY-2017 - UnderDev build).

This draft release, developed using Rhp 8.2, has a number of accumulated updates/fixes. The most notable are that the ElapsedTime actor is now automatically wired in when you first create a simulation block hierarchy (Simple or Full Sim) and that the creation menus for events, operations, and attribute/checks are now more widely available on different diagram type canvasses. Note that the latter also fixes some missing menus found due to the introduction of ValueProperty new term in 8.2. As such, nothing urgent but I'd recommend anybody currently using v2.1.e to move up to this version when they can to get a more "as designed" experience.
