Fixed a race conditiony Lua error in properties.lua
Fixed certain "Entity Get Count of X" functions returning nil
* GetNumPoseParameters
* GetBoneCount - used to return -1, now returns 0
* GetHitBoxGroupCount
* GetHitBoxCount
* GetBodygroupCount
Return empty string on failure:
* GetPoseParameterName
* GetSequenceName
* GetSequenceActivityName
Minor cleanup
More Entity no nil returns treatments
Return 0 on failure:
* GetSkin
* GetSequence
* GetNumBodyGroups
* GetSequenceGroundSpeed
* GetSequenceMoveDist
* GetModelContents
* GetLayerDuration
* GetLayerWeight
* GetPlaybackRate - returns 1 on failure
* GetBoneName - returns __INVALIDBONE__
* GetSequenceActivity - returns -1
* GetSequenceVelocity - vector_origin
* GetLayerPlaybackRate - returns 1
Adjustments to singleplayer clientside lua file stuff
