Added a comment concerning NIM_SETVERSION.

Added a comment to remind me of the unsolved problem around NIM_SETVERSION.
AutoSave now lets the user finish their action before saving.

Added a check that postpones saving until there is no input.
This is implemented by checking the state of all virtual keys
from 1 to 135. (VK_LBUTTON and VK_F24 resp.)
Also added a unit test for this new function.
Changed text color of empty list controls to gray.
Changed wording on the "Create a Connected Shortcut" dialog.

The instructions now are above the list views instead of inside.
This way, the user can still read them after dropping a file.
The text inside the empty list views now shows a generic, meaningless
status message.
Updated the TODO file.
Bumped to version 0.9.3.
