Added certificate to Dev builds.
Fix build.xml
fix typo.
Copy paste typo + cleanup.
Move SimpleID to router, add a used/free set to avoid ever-growing BitSets.
use int instead of UUID, and ArrayList<x> vs HashMap<UUID,x>

didn't update the new firewall node, as i'm not sure how to make it save
and load.
second half of previous commit - compiles and world loads

routing seems to be a bit derped, crash of pipe removal.
need an extra npe check
change the routing table to be an array list

much faster access

also changed the locking mechanism on the LSA table, as writing to an
element of an array doesnt have thread contention.
avoid simpleID of 0

this means that unitialized items don't detect as being correctly
routed.
true fix for the previous issue.

will keep the previous patch, so that any future code issues dont' break
things at random.
