Writes out a full PALETTE.DAT-formatted file named <filename> with the
base shade table numbered <palnum> and the base translucency table
numbered <blendnum>.
Finally, you are asked to specify additional blending tables that can
be stored in EDuke32's extended PALETTE.DAT format. If one or more
additional blending table is specified, you are also queried for the
log2 of the last alpha blending table index, <lognumalpha>. Since alpha
blending tables are assumed to be set up at indices 1 to
exp(2, <lognumalpha>), it is also the log2 of their total count.

Overwrites the water base palette with one where each 16-tuple

Creates a shade table for debugging purposes at pal <palnum>.
