FieldCare

New:
Added a dedicated medical window opened with H.
The window can be moved by dragging its title bar.
Pressing H again minimizes it to the nearest side of the screen.
Pressing H while minimized restores it.
Escape and the title-bar button also minimize the window.
Window and dock positions are remembered between sessions.
Treatment buttons show available Bandages, Splints and Medkit charges.

Changed:
Removed the medical panel from the vanilla inventory.
Treatments now automatically use supplies from the player’s inventory.
Updated the treatment instructions and interface text.
Updated networking for the new treatment controls.
FieldCare must be updated on both the client and server.
