[DEV] Shattered Pixel Dungeon v2.4.0!

Hey Dungeoneers, Shattered v2.4.0 has been released!

v2.4.0 features a new category of item: trinkets! They are more about tweaking gameplay variables than giving direct power or utility. There are also a bunch of smaller additions and tweaks, most notably to the Duelist and to Alchemy. Be sure to check the changes screen for full details.
