input: motion: do selection update even if cursor is outside the grid 
Previously, the selection was only updated when the mouse cursor was
inside the grid. This makes it difficult to e.g. do large selections
fast, since you often end up moving the cursor outside the grid, or
outside the terminal window even.

Now, we update the selection regardless of *where* the cursor is. This
is done by bounding the row/col we pass to 'selection_update()' to the
grid, while still setting the seat's row/col to -1 when the cursor is
outside the grid, to ensure the xcursor etc are set correctly.

Care must also be taken to *not* pass any motion events to a mouse
grabbing client, when the cursor is outside the grid.

Closes #70.
