Added spawn flag for func_tracktrains to skip updating its yaw angles as it moves.

Added new "Player Invulnerable" spawnflag for trigger_camera to stop players taking damage while the camera is active.
New spawn flags added for the xen plant entities (xen_hair, xen_plantlight, xen_tree and xen_spore_small/medium/large) which make it easier for mappers to place them in a natural looking way:
- "Drop To Ground"
- "Random Angles"
- "Non Solid" - Only applies to xen trees and xen spores and trees.
Func_breakable and func_pushable entities have the following changes:
- New spawnflag "Immune to Clients" - Cannot be damaged or broken by players under any circumstances (except when triggered to break via the "Only Trigger" spawnflag).
- New "Classify" key. When set to "Player Ally" (11) or "Human Passive" (3), can only be broken by players when the cvar "mp_npckill" is 1. Immune to players but damageable by monsters when "mp_npckill" is 2.

New entities item_helmet and item_armorvest, as they appear in Blue Shift.
Trigger_change_class entity can now work with Players. This allows players to have their classification overridden.

Trigger_changevalue and trigger_copyvalue now support setting entity state and flag bit mask variables with original identifiers from the code. ("FL_NOCLIP", etc.) Leading ~ will perform bitwise negation.
Trigger_changevalue and trigger_copyvalue now support setting entity edict keyvalues. For trigger_copyvalue, source keyvalue can be left empty to treat the source entity as the edict_t* to be used.
Added feature for mappers to set custom keyvalues to store variables on entities.Use the following prefixes:
- $i_name for integers (whole numbers)
- $f_name for floating point numbers (decimal numbers)

Fixed trigger_hurt_remote list memory management, list iteration and unwanted toggling behavior in the "non-constant" mode.
Changed the map voting list to use the unreliable message channel to help free up the reliable channel for more important data when players join.

If developer is 2 (or higher) the sound engine will print a list of sounds it successfully loads along with fails.
Deleted CVAR "sv_admins" for a list of server administrators, as it is limited to 128 characters. Instead list your server administrators in a text file pointed by CVAR "adminslist" [default "admins.txt"]. You can have up to 256 administrators in this file.
Fixed warning "doesn't have a landmark" not having a newline ending, meaning the next console/log message was stuck on the end of this warning.

Major Bug Fixes

Fixed a server crash for when a player picks up the shock rifle while holding no weapons.
Fixed picking up dying shockroach exploit.

Restored ability for entities to trigger themselves, with a recursion level limitation of 128.
Fixed trigger filtering "classname out" from not working at all.

Fixed snark spawning crash bug when monster_sqknest placed independently in a map.
Fixed null pointer dereference with baby headcrab death, which lead to a game crash if their attacker was gibbed.
Fixed game crashing if sound/model replacement file lines are not perfectly formatted ("original" "replacement"). Mappers can now use comments (# and /) and blank lines to help organise them easier.
Fixed env_beam crashing servers due to sending a new network message without finishing the current env_beam network message first -- only effects env_beam with the ring flag enabled.
Fixed FMOD initialization error 79 when attempting to use too many input channels for the sound card (fall back chain: 7.1, 5.1, Surround (4.1), Quad, ProLogic/ProLogic II (5.1 encoded over Stereo), Stereo, then Mono)
