docs: Update installation document 

Various installation updates.  Recommend upgrade to OctoPrint v1.3.0.
Recommend configuring OctoPrint to not disconnect on error.  Note
quirk with needing to reload page if "/tmp/printer" not in list of
serial connections.  Add brief documentation on use of extended
commands and checking for errors.

main page) make sure the "Serial Port" is set to "/tmp/printer" and
click "Connect". (If "/tmp/printer" is not an available selection then
try reloading the page.)
Once connected, navigate to the "Terminal" tab and type "status"
(without the quotes) into the command entry box and click "Send". If
the Klippy config file was successfully read, and the micro-controller
was successfully found and configured, then this command will report
that the printer is ready. Klippy reports error messages via this
terminal tab. The "status" command can be used to re-report error
messages.
In addition to common g-code commands, Klippy supports a few extended
commands - "status" is an example of one of these commands. Use the
"help" command to get a list of other extended commands. In
particular, note the "restart" command - use this command to reload
the Klippy config file after any changes.
