Tony Sergi fixes integrations part 2 - networked animations

[AdamTadeusz]

Description

Adds Tony Sergi's multiplayer_animstate.

Decided to drop neo_playeranimstate, hl2mp_playeranimstate does not differ that much from what we need for the neo player, but can revert it and multiplayer_animstate and put all the changes into neo_playeranimstate instead.

For the reviewers, unless you do not trust Tony Sergi's changes, I suggest clicking on the commit that he authored and marking all the changes there as read separately, should cut down on the amount of changes needed to be reviewed significantly.

[Edit] actually it seems that commit also contains my conflict resolutions so that won't work :(.

Still need to do some cleanup, should probably repurpose the old neo_playeranimstate to now includde the changes in hl2mp_playeranimstate and multiplayer_playeranimstate

lgtm but I'd like a proper test with lag compensation. EU host and we run through all the animations.

fakelag be damned I wanna see this forreal

Still some animation looping issues with assault's head and grenade idle animations appear to be playing faster than they should.

If you look at the animations in half life model viewer they do actually do those head movements. I think it's just a case of the upper body animations being slower in the original than they are currently in this branch, or maybe its tied to the player speed or something.
