* Rename Mapper (too generic) to Minimap * Add lua functions to get/set position, angle, mode for minimap * Client: rename m_mapper to m_minimap * Add minimap to core.ui namespace (core.ui.minimap) * Add various functions to manage minimap (show, hide, toggle_shape) * Cleanup trivial declaration in client
