Updates

Converted Read-Host (console input) in CreateProject.ps1 over to a GUI
pop-up box, as per requirements (also automatically populated the text
box with "YYYYMM-" ).  Updated CreateProject.ps1 to create folders in
the Projects\ subdirectory of a subject folder, which also removed the
need for special "create directories" permissions for Non-Admins.

Rolled CreateFolderStructure.ps1 code into VerifyFolderStructure.ps1.

Added <li class="recent"> tags to folders created less than 30 days ago
in the index.html file.

Tested all code to date, including running CreateProject.ps1 as a
non-admin account.

Started to clean up some of the code clutter, but there's more of that
to come once all the functionality is done.  Still have to add config
file functionality (user-configurable Data folder location, as well as
"ignore" folders for the tree walk).  Also need to refactor and revise
HTML generation code (adding top-level shortcuts, and eventually
allowing for use of a template.)
