Fixes UI icons staying open and crawl text

[Semuca]

Purpose

Fixes #6088 and adds crawl text (One of the health rework issues).

Notes:

In UI_ItemSlot.cs, I've moved some duplicate code into it's own function and added a test that checks if the item slot is hidden or not before displaying the placeholderImage, which caused those 'phantom icons' to appear.

Changelog:

CL: Fixed UI icons staying open
CL: Added standing up text

It isn't now, unfortunately ; ). Merge conflicts - just overwrite my changes and then re-namespace 'em.

does it fix this line on the health issue?

when you try to get up after crawling, it displays the same text "You try to lie down."
