Cavegen/Mgv5/Mgv7: Add optional giant caverns
Add to MapgenBasic for use by multiple mapgens. Add to mgv5 and mgv7, enabled by default. Similar to mgvalleys caverns but half the scale. Parameters for upper y limit, distance caverns taper to full size, and noise threshold (full cavern size). As with mgvalleys caverns are generated first and classic caves are disabled in any mapchunk containing a cavern, to avoid excessive spreading volumes of liquids. This also avoids floating blobs of liquid where a large classic cave has overgenerated out into a neighbouring previously-generated mapchunk.
