developing branch: gen_icon function name clash

[CJDumbleton]

Re 'developing' branch: I made a mistake forgetting to rename the gen_icon(non_ir) function gen_non_ir_icon(non_ir) or similar. It clashes with the gen_icon(dev) function. Alternatively, you could combine gen_icon(dev) and gen_icon(non_ir) and pass in the type key as an argument. Do you want me to fix it and do another pull request?

thank you very much, I am working on it
