[Therion] Stupendous symbol effort

I just noticed yesterday's development update. An amazing effort Rodrigo, adding all of those new symbols. They will be much appreciated I am sure - I can already think of existing maps of mine that I might update as a result. I don't want to be too picky, but I wonder about the use of plural 's' in for some of the symbol names. I have attached a screenshot of the Therion Book page 24. I think symbols such as 'discs-pillars' should instead be named 'disc-pillars'. But of course English being English there are exceptions to the pattern, such as 'pillars-with-curtains' and 'stalactites-stalagmites' which are probably OK. Bruce
