Make Nexus startup script LSB compliant

I recently ran into the following error with  Nexus and Debian:

warning: script 'nexus' missing LSB tags and overrides insserv... 

which causes a loop within insserv. This is due to a non LSB compliant startup script of Nexus. To make your nexus startup script LSB compliant add the following stuff at the beginning:

#! /bin/sh

### BEGIN INIT INFO
# Provides:          nexus
# Required-Start:    $remote_fs $syslog $network
# Required-Stop:     $remote_fs $syslog $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Nexus Maven Proxy
# Description:       Nexus Maven Proxy
### END INIT INFO

Then run:

# insserv nexus 

and you are done.

Insserv is now aware of preconditions for properly starting and stopping Nexus.
