Add Easy Access menu and more App. Tools options

Added an Easy Access menu and tried to replicate features from Windows
8's File Explorer, specifically the Pin to Start, Include in Library,
and Add to Favorites options. (Map to Drive will not be possible without
extra work.) Also added Pin to Start and Run as Different User options
to the Application Tools tab, both highly requested features. However,
of all those things I added, only Add to Favorites works right, and
that's because it was existing code. :)
