Invert selecting no objects causes all selected objects to be deselected

[Nathan Schulte]

Invert selecting on an empty area, either by lasso or by click, causes all selected objects to be deselected. The inverse is not true, nor should it be after the bug is fixed. Invert selecting on nothing should invert select nothing and not change the state of the current selection.

Here is a patch with some code style and formatting changes I made while researching this bug. This is against current master HEAD, not against the patch submitted as solution for the bug (the above patch).

    gschem: Fix a bug with invert selection

    When invert selecting "nothing", all currently selected objects are
    deselected. This is annoying when you "miss" trying to invert select a
    small group of objects. This is now fixed such that "missing" and
    selecting "nothing" does not deselect everything.
