Fixed: hitTest method returns the wrong view in the CPTableView when the selectionStyle is set to CPTableViewSelectionHighlightStyleNone

Previously, when having a CPTableView with a selectionStyle set to CPTableViewSelectionHighlightStyleNone, we needed two clicks to be able to select or click on a control of the cell. Now we only need one click as in Cocoa.

This is fixed by changing the method hitTest and returning the good view which can become the firstResponder.
