Display IP to user after install
Added code to display the web page IP they should use to log in to the web UI, in case the user does not know how to find it themselves.
Re-orded the final text to make it the next steps more obvious.
Merge remote-tracking branch 'vanosg/displayIP' into displayIP
Removed instruction to edit config.cfg (not needed for most users). Fixed typos
Removed install code for wifi checker, because it moved to updateCron.sh
