commented out glue code that isn't public build ready

displays a preset list of hosts and their response state

Updates format of input file to CSV with <host ip>,<host name> as the format.
UI now has red/green for down/up hosts
duration_to_string now in lib
improves display of how long ago change happened
log events are now displayed on the monitoring page to show when a host comes up/goes down
Modularize ui better
Adds ability to return to monitoring or quit from editing page
table in place for displaying hosts

WIP: start of being able to go up/down through the list of hosts to eventually edit them.
