Fix "invalid format PHY" for old model formats
Add non-halting error when tables have wrong data type
* This relates to C functions that expect table inputs. Instead of failing silently, we let the developer know they are doing something wrong
Delete particle_test* convars/concommands
* Seem useless?
Delete simple_bot (simple_bot_add concmd)
* Nextbot test entity or something?
Delete hunter_shoot_flechette concmd
Delete fadein and fadeout console commands
* I think that this is never used?
Fixed a number of concommands crashing when using on srcds
* For example `prop_physics_create`
Give weapon_cubemap a unique bucket position
* So it doesn't conflict with other built-in weapons. really should update the weapon selector so this isn't even necessary
Disable most impulse commands
* This includes 76, 81, 82, 83, 102, 106, 107, 108, 195-197, 202 and 203
* All of these are either useless or do nothing, or are replaced by Sandbox. (jeep spawning)
Remove some CAI_BaseNPC debug stuff
Removes CAI_BaseNPC::m_pDebugNPC, SetDebugNPC, IsDebugNPC which are never used
Remove CBasePlayer::m_rgItems (unused)
Enable default weapon selector to render weapon slots 7-10
* They will not appear by default (as empty boxes), but if you have a weapon in slot above 6, you can now actually see it
Move where model scale limits are enforced
* Also delete duplicate m_flModelScale definition in the data table
Rework weapon selector weapon positioning
* It kinda took too long, but it is no longer possible for weapons to be invisible within the first 10 slots. Everything else should be the same
* Removes a few SlotPos related hacks
* Fixed slot 10 (bound to 0 by default) having wrong number in the selector, and not being selectable via the bind
