(pre) V0.19 a small update while we finish the next boss

CONTENT : * 6 new unique items to discover (while we put the finishing touches to the new boss fight) - Defibrillator - Moebius's Drive - Duke's Cell - Backstabber - Zealot's Blade - Stubborn Plate

FIXES : - Fixed a graphical bug on the Sand Shard environment - Fixed a bug where some automatic skills triggered by enemy deaths did not work properly with the freighters (boss).

KNOWN BUGS :
* If you change keybindings or remap your pad with the second launch option, you have to always use this second launch option to use your edited settings. We're quite aware it's really not satisfactory but it will probably force us to refactor a good portion of our control management through a dedicated plugin.(In progress)
