Subject: * Terrain uploads via the Estate Tools now support a multitude of
 file formats. Specifically: . bmp, .raw, .r32 & .r64. (in ascending order of
 precision) * It uses file length as the detection routine (as each of these
 formats has a distinct size in bytes for a 256x256 array.) - more formats
 should be possible to add.
