Synoptic: Displayed Icons

As an instrument scientist I want the icons on my synoptic to relate to what the device is monitoring/controlling, and for there to be icons for items not under computer control.

** Acceptance Criteria **
1. There is a wider range of icons for the synoptic, and associated lists of target device screens can be loaded
1. This extended list needs greater detail

** Notes **
1. Examples for this would be:
1. Power supplies which can control different types of magnet, or a spin flipper, and be different manufacturers/models such as Kepco, Danfysik, Genesys...
1. Temperature sensors, which could related to a location/other item such as the sample, analyser, or detector, and be various manufacturers such as Eurotherm, Lakeshore, Mercury...
1. Some suggested icons from James Lord:
1. VAT valve (in-line) (item not controlled from IBEX)
