tweaked: JIP/isdedicated bug when adding actions in multiplayer (WIP)

fixed multiplayer addaction code

added leash action to add/remove/reattach leash at will
tweaked attack AI while on/off leash
added server command to send actions to multiplayer players

removed action to load/unload k-9
k-9 automatically boards vehicle of owner and disembarks when owner gets out
added parachute to k-9 when owner ejects in the air and k-9 is above 150 meters
tweaked: attack automatically stops after bad guy dies

hotfix for hideobject

Added leash (Thank you duda for the technique)
Tweaked movement when K-9 runs to end of leash
Tweaked command names

added respawn capability by setting time in seconds between death and respawn
fixed petting k-9 action, works with all dogs for all players (including other dogs placed without this module)

changed object type from agent to unit to support future multiplayer plans
adjusted movement speed thresholds

Added option to get in/out k9 from vehicle so your dog can travel with the owner

added "Pet K-9" option for owners (WIP) // TODO: make it possible for any players to pet K9
