Gloomhaven updated monster standee base and openscad sources

Now that I have Gloomhaven, I have updated the Monster Standee Holder to be more functional!

Moved the current hit point indicator to the front (recommend sharpie to darken tip)
Moved the condition holder to in front of the Standee holder so you could see them! Duh!
Same great number spinners (also recommend sharpie to make the numbers stand out)
Same great standee holder
