Pathfinding Avoidance

Make pawns try to avoid certain areas, such as filth-generating terrain or configured doors.

In vanilla game, pawns do not mind walking through a freezer, other pawn's bedroom, or cutting a corner of a paved path. This mod implements the following features:

1. Filth avoidance - All terrain that generates filth will be perceived as more costly to walk and pawns will try to avoid them if a clean path is nearby.
   
2. Door avoidance - Each door can have a priority set. Pawns will try to avoid using 'Side Door' doors, and will use 'Emergency Door' doors only if it is the only way or the alternative is very costly.
   
3. Area avoidance - If allowed areas named (exactly) "Path Avoid Low", "Path Avoid Medium" or "Path Avoid High" exist, these areas are perceived as more costly to walk. These areas cannot be assigned to in the Schedule/Animals/Mechs tabs.
   
4. Growing zone avoidance - All growing zone tiles will be perceived as more costly to walk and pawns will try to avoid them.
   
5. Room avoidance - Visiting friendly pawns (such as trade caravans) will try to avoid colony rooms; indoor rooms more than outdoor ones.

(Features 1. and 2. match the non-performance features 'clean feet' and 'doorpathing' from the Clean Pathfinding 2 mod. Feature 3. is similar to the functionality of the Path Avoid mod.)

These rules apply only to non-animal colonists or non-hostile visitors. Certain exceptions apply,
such as being drafted, in mental state, bleeding severely, doing emergency work, fighting, fleeing, etc.

Pathfinding code in 1.6 is well-designed with regards to performance, with extensive caching and reusing of data, greatly reducing the need to update pathfinding data. This mod is designed to be cheap, with its performance impact being insignificant. Moreover changing settings to use 0 cost disables related parts of the mod. If you encounter a case when the performance impact is noticeable, please file a bugreport.

• Better Pawn Control - Rules ignored if emergency state is active.
  
• Hospitality - Guests use colonist rules while staying at a colony.
