Experimental AutoJCE & Reactor's incorrect parameter

[EXPERIMENTAL] Added the AutoJCE feature to the server source. This is expected to solve the encryption size issue without resorting to overwrite the JCE files on the system.
LMPQ now sends players to random starting rooms, GMS-like.
Added a server flag for the free market item sold announcement.
Tweaked the reactor-hitting system, expecting to solve the incorrect parameter issue on the "multiple players hitting" scenario.
