0.4 Uploaded

A few quick updates ran this from 0.1 to 0.4 in record time:

• Extra effort didn't cost breath in 0.1.  Fixed that, reupped as 0.2.
• The dungeon table had DS's instead of "go roll an encounter", as an remnant of a first-draft bit.  Fixed that, reupped as 0.3.

Then:

• Added a one-page intro and setting,
• Rewrote the 'for the referee' page to match the new setting, added barter notes.
• Added some more art.
• Reupped as 0.4
