Human NPC's "searching enemy" behavior had been pretty bland. I made some improvements for this behavior:

- Each NPC will have a "courage" value determined by his squad's condition, his health condition, and weapon

- When this NPC decides to search for an enemy that vanished from his sight, depending on the courage value, he might:
-- Rush to the last know position of the enemy
-- Wait there and aim at the last know position of enemy for some time
-- While aiming, walk towards a random position to search
-- While aiming, crouch-walk towards a random position to search
Overall, making NPCs less "dumb aggressive".

- When NPC is crouch-walking while out of your sight, you won't see the noise circle until he's very close.

- Added more "SHIFT+Click / RightTrigger + A" usage in the inventory:
-- To move item from backpack to planting UI's seed/fertilizer slots
-- To move an item back to the trader
-- To move an item into motorcycle's fuel/scrapmetal slot
-- To move an item into an interactive object's slot
And now when you quick-move items into a slot, it'll move 1 count of it each time you shift+click. For example, with the grain mill, which needs 4 seeds, you just shift+click 4 times to move 4 seeds.

- You can now quick-move a tool item in the backpack into the TOOL slot and replace whatever is already there.

- Fixed some bugs with the jumping/rolling animation. It used to cause player to hop into the sky whenever the frame rate is low. After some coding overhaul, jump and falling feel a lot more natural now and is no longer affected by frame rate.

- Fixed a bug with applying bandages while crouching which caused player to be visible to enemies.

- Added better error prompt when player tries to use G to quick-throw a non-grenade item such as the stink gourd. G for Quick Grenade is only used for grenades, to prevent player from panic-smashing G and wasting an item when they don't have a grenade equipped.

- Forced an achievement check for "Pulitzer" achievement whenever the game loads, in case the Steam API somehow missed it.

- The Blessed rock and rock of rejuvenation in Ravenwood will no longer make item disappear if you put an invalid item in it
