EXT-7075 FIXED Map button now is always enabled and shows current user location if no other item is selected

- Added new pure virtual member function isSingleItemSelected() to the LLPanelPlacesTab. It is used in the LLPanelPlaces class inside onShowOnMapButtonClicked() to check if something was selected on the active panel. If so then selection is shown on the world map. Otherwise current agent position is shown on the world map.
- Implemented isSingleItemSelected() in the both LLPanelPlacesTab derived classes: LLLandmarksPanel and LLTeleportHistoryPanel
- Removed functionality which disables Map button if no selection is made
