Change running from pi home folder to any specified user home folder

[peeejayz]

Personally I prefer to run things outside of the Pi home folder and in a specific account for ERLT.

This is more a security and monitoring reason.

Creating a global variable across ERLT for this reason called ERLTHOME

Changing the code to /home/pi/EasyRaceLapTimer to $ERLTHOME should be an easy change in the code to make this run from any home folder.

Then just setting up your /etc/rc.local to point to the account(erlt in this example):

(sleep 1; /home/erlt/EasyRaceLapTimer/ir_daemon/ir_daemon > /var/log/ir_daemon.log 2>&1 &) || /bin/true
(sleep 1; /home/erlt/EasyRaceLapTimer/web/start_sidekiq.sh > /var/log/sidekiq.log 2>&1 &) || /bin/true

Currently getting the code to run from another account/home folder is a nightmare and takes alot of digging about to make it do so.

I'm also looking into making changes to the code within my own fork to make everything run under a user account and not just making it all run as root - this is a big security risk, while its only a laptiming system, to be taken seriously this needs to start happening.

Let me know your thoughts - I'm coming from a Systems Admin Point of view over a coder - these are the sort of things I am trained to pick up on.
