fix: Match accuracy for pathing, walktriggers, and collision

[mark-b5]

The current engine implementation for pathing and walktriggers is some bastard hybrid between authentic 2004-2007 pathing and the OSRS pathing updates in dec 2013, due to a lack of information when it was coded

After reviewing lots of footage, the following changes have been made:

• Red X clicks no longer use serverside pathing
  • Since the client doesn't send over path calcs for unreachable npcs, this causes moonwalking. It turns out that the "bug" in the following thread was authentic:
    • Movement bug with clicking pathing entities 2004Scape/Server#974
• Walktriggers now always run in the opclick handler, and will only run once during the player's turn
• Ctrl-run will work for red-X clicks now. It was broken between Dec 19, 2013 and 27 March, 2014 in OSRS, but should have been working pre-osrs
• Player serverside pathing is now naive. This means players will get stuck on obstacles when trying to repath towards their targets!

Made some further changes to match edge cases. I think I have every case matched!!

The pathing rules are as follows:

• Player will path 'naively' to the target once the player is at the last or second-to-last waypoint tile
• New: If the player's current path is sent from the client, once the player switches into naive mode, the player will only choose a single naive tile and then won't repath until the player reaches it. This is what causes the player to get corner safespotted on obstacles.
• New: If the client sends over a waypoint underneath the player, the player will not repath later in the tick, which is what causes the "I can't reach that!" when npcs path away the same tick player clicks them

Rebased this PR to target 274, fixed the last few pathing edge cases, and fixed collision

This is new as well. Previously the cat would not get stuck on the guard here. Players and Npcs now refresh their zone presence when they have a waypoint, even if they are not actively moving, so the cat gets stuck

These changes should affect all branches, if that's feasible. This PR is now ready to merge
