A small update today--8 new rogues and monsters added, including a bandit, naga, centaur, druid, and others. (I also made minor tweaks to the palette)

Thanks to everyone who filled out the feedback form--it's proving extremely helpful to me to understand what people would like to see added.  It's clear that items and proper environment tiles need to be addressed next, although I'll still be updating with the odd monster or rogue sprite here and there.
