UI updates and throwing changes

Hey, I'm going to try and keep regular devlogs of all the changes happening in Recreant. Development has been moving quite steadily for the last few months and I work on the game most days, so these updates will hopefully be very regular. 

Today's update saw a number of UI changes, mostly tidying up bugs with some leftover data from examining NPCs with professions and other creatures without, along with some other minor issues surrounding cancelling targeting actions and funny situations like that. But importantly, I added a conditions list to the stat display UI on the left-hand side of the screen which will display all the possible conditions in effect, which at the moment include: poison, rot, satiation, intoxication and illumination. This also should work for NPCs so you will be able to see who's drunk and who's not.

Another change was the removal of the useless character sheet button and the drop item button, because the inventory button took care of this anyway. In their place has been the up and down stairs buttons and the zoom in and out buttons - all of which were keyboard commands but were undocumented. 

Previously throwing items was limited to throwing weapons and various valuables and that was activated from the inventory screen, but now you can throw anything with the new throw button and keyboard command. Most things won't do damage but it allows flexibility if you wanted to do weird things by throwing your armour around for whatever reason you like. It does let you throw food which might attract NPCs and some edge cases like that, so it's potentially useful and I expect will be more flexible as the game grows.
