1) Merged with mainline dev branch. 2) Removed assumption in homeassistant/__init__.py that states are visible if not specified. This assumption is intrinsic in the JavaScript. 3) Recompiled frontend to assist merge.

/**************************************************
The following code gererates line line graphs for devices with continuous
values(which are devices that have a unit_of_measurment values defined).
On each graph the devices are grouped by their unit of measurement, eg. all
sensors measuring MB will be a separate line on single graph. The google
chart API takes data as a 2 dimensional array in the format:
DateTime, device1, device2, device3
2015-04-01, 1, 2, 0
2015-04-01, 0, 1, 0
2015-04-01, 2, 1, 1
NOTE: the first column is a javascript date objects.
The first thing we do is build up the data with rows for each time of a state
change and initialise the values to 0. THen we loop through each device and
fill in its data.

# To script is for running Home Assistant as a service and automatically starting it on boot.
# Assuming you have cloned the HA repo into /home/pi/Apps/home-assistant adjust this path if necessary
# This also assumes you installed HA on your raspberry pi using the instructions here:
# https://home-assistant.io/getting-started/
#
# To install to the following:
# sudo cp /home/pi/Apps/home-assistant/scripts/homeassistant-pi.sh /etc/init.d/homeassistant.sh
# sudo chmod +x /etc/init.d/homeassistant.sh
# sudo chown root:root /etc/init.d/homeassistant.sh
#
# If you want HA to start on boot also run the following:
# sudo update-rc.d homeassistant.sh defaults
# sudo update-rc.d homeassistant.sh enable
#
# You should now be able to start HA by running
# sudo /etc/init.d/homeassistant.sh start
