RLGWebD: rlgwebd.js annotate

annotate rlgwebd.js @ 28:2ad2b6491aa9

rlgwebd.js: become a real daemon. The RLG-Web server now forks off, writes to a logfile, and reads from a control socket. Unfortunately it can't handle the problem of another rlgwebd process already running. Maybe a lockfile would help.
