Fail in load home at linux

[tech-josemanuelrincon]

When launch log.io-harvester with other non root user or supervisor, dont load correctly home

I have changed this in bin/log.io-harvester

+osenv=require('osenv')
-homeDir = process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'];
+homeDir=osenv.home()

This changes, fixed the problem above

v0.4.3 no longer requires root/sudo to install, so that should address this issue.
