Add swallow and explosion glyphs to glyph_to_cmap

Browse Source 
This makes custom S_sw_tc etc. from Enhanced1 symset actually work,
yielding nice smooth outlines for swallowers and explosions. Or so I
think, I have only tested the former because when playing locally,
explosions disappear so fast I cannot see them.

While looking at where else glyph_to_swallow was used, I noticed that
parse_id subtracted S_sw_tl from glyph_to_swallow, even though it
returns 0 to 7. This looks like it would cause out-of-bounds access and
perhaps a segfault when trying to customise glyphs for individual
monster swallow glyphs (or whatever it is parse_id is used for), but
I haven't tried to confirm nor change this because who would ever do
such thing?
