Core/Maps: Implement optional pre-loading of maps.

- Option to preload basemaps upon server load (BaseMapLoadAllGrids)
- Option to preload instance maps upon map load (InstanceMapLoadAllGrids)
- Change default logging to only log mmap errors to server log
- Add new public to map to load all cells in map
- change debug loadcells to use new function instead
