Moved wxPGChoices m_choices member from various property classes to base wxPGProperty. This allows any property to have choices without subclassing and therefore work with Choice and ComboBox editors. Also removed redundant choice manipulation functions from wxPropertyGridinterface (ie. now use ones in wxPGProperty).
