Visual Studio 2017 changes the on-disk format of the user cache for TFS

workspaces, and Team Explorer Everywhere and the TFS Java SDK don't have

support for the new format. This meant that our two methods for interfacing

with TFS on the client would not work against VS2017 workspaces.
Fortunately, the tf.exe command-line tool that ships with VS2017 restores

some of the features that were removed in VS2015 (which prompted our move to

Team Explorer Everywhere), and is sufficient for posting pending changes. This

change implements support for that, and adds some documentation about the three

TFS methods and how to use them.

Posted a few TFS changes involving edits, adds, deletes, moves, and copies on

  various types of files, including binary files.
Built the docs and looked at the new page.
