Minimap as HUD element with API control

Browse source 
Features:
 * Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes()
 * New HUD elements for displaying minimap with custom size and placing
 * New minimap mode for displaying a texture instead of the map
