Modified methods used to set/unset wxPGProperty as read-only and to hide/show it.

Browse Source 
If there is requested to set/unset a single property (without recursion) as a read-only (wxPropertyGridInterface::SetPropertyReadOnly) or to hide/show it (wxPropertyGridInterface::HideProperty) then first check if property is already in the requested state and if so do nothing. This prevents from unneeded refreshing of the display.
