hay you guys posting on this site gives me good luck   
i found it all on my own (the regular ship cap)
in case anyone is intrested
there are files that are called MAXSHIPSLOT they are for every level of the slot upgrades ingame for instance
RESEARCHSUBJECT_MAXSHIPSLOTSPSI0

this is the file for the first upgrade of the ADVENT
inside it find this sagment

modifierType "ShipMaxSlots"
baseValue 100.000000
perLevelValue 150.000000

and change base value to how much you want it to give you hopes this helps those who didnt know ad by the way the next files all have zero in base value so i guess the perlevel value is also important

another thing i found is where to edit "buildings"
you need to find something that starts with PLANETMODULE

for instance PLANETMODULE_PSIORBITALBEAMDEFENSE.entity

this is the ADVENT beam defense inside it you can edit cost and time to build
just thought i would post it for future refrence hopes this helps
