Custom temperature graph also for hidden sensors

[marin849]

I have so many temperature sensors that I have hidden a lot of them, and assigned them to different locations to be able to view them as needed.
This works, because it takes a long time to display the page with all sensors otherwise.

However, I just noticed that they are also hidden from the list of sensors possible to select for a custom graph, which is unfortunate as it is a good way to compare temperatures over time.

Suggestion: Create a check box "Show hidden sensors" in the custom temperature graph view, or simply just show all sensors in the list.

Extra suggestion: Sort the sensor list in custom temperature graph in alfabetic order instead of SensorID.
