Paint selection stacks

Paint selection in visual mode stacks, i.e. the same thing/surface can be selected multiple times.

Further experimentation has led me to believe issue #519 and issue #520 may be the same.
When adding paint selection to the same surface or thing, in visual mode, the selection stacks. Actions such as raising/lowering things, and panning textures, will multiply(i.e. a thing with two added selections will be raised twice 16 units instead of 8 when scrolling up one tick).
When a thing/surface is deselected, it shows as deselected(No flashing indicator; "Nothing selected." shown in statusbar), but actions such as raising/lowering things, and panning textures, will still be applied as if the things/surfaces were still selected.
The exception seems to be if one clears selection(Default key: C).

Fixed in d65fb7b. Cause was the same as for #519.

Doh! The fix only worked for the highlighted object when starting paint selecting, but not when moving the mouse. Should be fixed for good in 3fbad3c.
