Updated Light & Switch Functionality

[FyrbyAdditive]

Hi, this is my first time attempting to contribute someone elses project on github! Anyway, here is a summary of the changes:

• Ability to optionally change light and switch background colour, defaults to black if unset
• Ability to optionally add text to light and switch buttons, defaults to none if unset
• Ability to optionally choose different light and switch icons, defaults to similar icons
• This one I guess is subjective as you seem to have a preference for font-awesome, however I wanted to make it look more home-assistanty so the new icons are custom ones I have made based on MDI

Thank you for the work on your projects

HI @timtimellis

Thanks for this! I'd really like to get this merged, but I've just realised that tests fail for me:
