this is the first basic rules of kais mod.

added parentchildrule which currently only handles the removel of children if a parent dies, but will be extended to handle other actions based on event receiving that deal with child and parent association.

add keyword targetable ability "connect"
connect means "the source adds the target to it's parent vector, the target adds the source to it's children vector"
this can be multitargeted, so it is possible that 
"Big Bad Dragon" can live it 2 different domains. 
not sure if this was even asked for, but i thought it would be cool to be able to say
"to play big bad creature you need to give it 2 homes"
or
"big bad creature can live in upto 4 homes"
this adds a level of stratigy, becuase now big bad creature can have "all creatures which share a domain with big bad creature gain +2/+2"...or "all domains that city planner live in gain 1 capacity"
but also add the possibility of faster removel from a card like
"destroy all creatures on target domain".
i thought it would be a nice add to kai rules.

connect clears a target= on a card after connecting...this is to avoid abilities transfering to the target, unless you want it to effect the target like
"tap target domain as this becomes a inhabatant"
target=domain
auto=tap
auto=connect
auto=<==this line on will not be targeting the domain
