Add files of the program
Add log information to README files
Set type of all fields of zabbix template to Text
Add two samples with comments for Settings.py file
Add init script to manage the daemon

 - Add init script contrib/smonitor
 - Add pidfile parameter in Settings.py
 - Add creation of a pid file to daemon start
Improve init script

Now the script can creates the folder for pid file and set owner for this folder.
It's important because the daemon has user privileges and can't create a file in /var/run.
Edit parameter templates of commands

 - Replace short options with full name options if possible (e.g. -q to --quiet)
 - Increase timeout for arp-scan command from default 100 to 300 (it works better in wi-fi networks)
Add instruction about smonitor install
Add zabbix server requirement to README files
