Bugfixes and a layer of overall polish

The most visual change in this update is probably some layout changes I did for the interior of a huge frigate in the third mission. I split it into three sections divided by walls, so that only one section's contents need to be visible at a time, which helped a bunch with optimization. Here are some views of the renewed interior:

I also added a carriable horn that guards can use to alert nearest enemies on a radius. The player can use it too of course, if they wish to make a grand entrance or just want to see how the enemies react.

In addition, there are just lots of small bugfixes on the mechanics and missions, like the points below:

AI:

• fixed enemy door interaction animations not working when he's coming to view from a different room

• fixed enemies not following player to different rooms very likely

• enemies now wake up more easily

• enemies rotated suddenly

• enemies don't try to find weapons behind locked doors anymore (which was making them freeze)

Save/Load:

• bodies stay where they fell after loading game

• lit lantern wasn't lit after load, also the model is parented weird

• book was open when carrying after loading game

• fixed the character dropping to water when loading a save on boat

Interaction/Player Movement

• book's pages were blinking when turning page, and a letter's content wasn't visible in some cases

• fixed issues with lantern, like enemies not seeing with it, and the physics not working when carried by an enemy

• weapons can strike walls and make an impact sound

• falling ceased for the duration of flinching and two-handed attack

• Prevented carried torch clipping through walls with IK

• Prevented throwing grappling hook in tight spaces

Mission 1 pt2:

• figured out ways to make the scene optimized, while showing captured live enemies and dead bodies with numbers reflecting playstyle

Mission 2:

• level design tweaks, making it more optimized

• added some dead trees outside

• lighting improvements

• solved some problems with enemy visibility

Mission 3:

• splitting interior into 3 sections, updating the map

• added enemies inside cottages, improved the lighting and decoration in them
