Added a TODO list.

As of now, TODO comments should be saved in this file instead of in the code.
Changed compiler options for the Debug build.

Changed the run-time library flag from /MDd to /MTd.
Removed an unnecessary part of an unnecessary file.

There are no TODO sections left inside the project files except this one.
Now, it's deleted, too.
Removed a bug that prevented saving miscellaneous settings.

Overwrote the wrong MiscSettings object.
Another person might find a mistake like this embarrassing.
Removed a bug concerning NIM_SETVERSION.

We call Shell_NotifyIcon(NIM_SETVERSION, &nid) with
nid.uVersion set to NOTIFYICON_VERSION_4.
The call returns TRUE indicating success, yet it doesn't
change the icon behavior like it should. The icon does
not send WM_CONTEXTMENU on being right-clicked and the
wParam is not being set to the mouse coordinates.

Thus, we stop relying on NIM_SERVERSION. We query the
mouse position ourselves and answer to WM_RBUTTONUP instead
of WM_CONTEXTMENU.
Bumped version to 0.9.2.
