Added a check for root access.
Limited output from 'last' command to the 5 most recent logins.
Replaced deprecated backticks.
Made current login listing smaller and more informative.
Fixed spacing, added a few comments, made the Changed Files part only show up if the files are actually changed.
Changed the check for users that have a bash/sh shell to look for users that are able to login (to some kind of shell/application).
Fixed problem with empty variable checker on the Changed Files section.
Added more empty variable detection, fixed some formatting, added a listing of cronjobs in /etc/cron.d.
Changed the Top Processes section to show pstree instead. 'ps -A' is more info than needed.
More output and code prettification.
