Changes init script exit code to conform to lsb standards

Resolves issue #1016 
@jvshahid Isn't the one above (line 146) only exectued if the pid file exists, but the proceess doesn't? If so then exit code 1 would be the correct I think. 

lsb status codes

exit code | condition
------------|--------------
0	| program is running or service is OK
1	| program is dead and /var/run pid file exists
2	| program is dead and /var/lock lock file exists
3	| program is not running
4	| program or service status is unknown
5-99	| reserved for future LSB use
100-149	| reserved for distribution use
150-199	| reserved for application use
200-254	| reserved
