reduce number of strongpoints per system from 3,5,7 to 1,2,3,4.
point cap scaled with amount of strongpoints now:
a 4 SP system reaches 4x max cap but not min cap. This means:
- all systems can hold out 3.5 days if at full health at start no matter amount of SPs.
- side effect: more SPs in system = activating voidshield is faster. (1h -> 15 minutes)
max points are now 300 000. thats 3.5 days if you are at -1 station.
min points are now -3600, thats 1 hour to boot up the voidshield.
added voice announcer for strongpoint loss, capture, contested.
added voice announcer for entering stronpoint sector or shielded system.
