Data importer for factions does not take factions with sub-factions into account

[maxdekrieger]

Title says it all, this prevents Maruuk Centaur and Valdrakken Accord from being added automatically, as found out in #493.

Line 86 and 87 of the importer have to be changed into something more elaborate.

SimpleArmory/dataimporter/factions.py

Lines 86 to 87 in 6f2e259

	if not children:
	self.dbc_faction[int(rep['ID'])] = rep

Hey @maxdekrieger

Was this one solved on the recent PR? Do you think it can be closed?

[maxdekrieger]

It wasn't solved in the recent PR, I just added the non-leaf factions manually so this should still be open.
