- Added ref counting to TMaterial

- Added cache growing to TCacheManager
- Fixed ImagingOptions.inc to not include JPEG support
- Fixed TfrmRadar to save the radar map to the correct location
- Fixed statics using the wrong hue when being painted
- Removed obsolete TLandTextureManager.GetFlatLandMaterial (and the according cache)
