Enhance faction service so some factions can be excluded from gaining/losing points

[Undercova]

Problem:

The amount of factions that are listed in the official string files is currently limited.
To get more options about NPC vs NPC war we can currently add more factions that are not known to the system since they are not in the stf files.
When i add a new scenery where a new faction should fight another new/old faction i can easily add those to the faction sdb. they will fight fine vs. each other.
Problem pops up when you attack them and they spam your screen with messages of unknown faction strings.

Idea:

2 layers

• a faction can be created as you want it to be. you can also set the enemies as you want
• you get points or no points depending on a boolean setting in the faction database. no system message if FALSE

Solution:

Keep faction service as it is but exclude point granting/deduction if set in table.
Create a boolean column in the faction sdb where you can set if the faction will be displayed/counted when you kill a member of it

I have added a new colum called "SysMsg"

if TRUE = show and calculate like right now
if FALSE = ignore sending system message and the faction point calculation
