Adjust Clock Screensaver Settings

Add the ability to change the clock screensaver font type, size, and color.

I would like to suggest the possibility to change the clock into displaying a (MQTT) sensor state. I have for example a clock right next to my Wallpanel device, I would be way more interested in seeing the current room temperature as the screensaver's 'value'.

While MQTT value would suffice for this, a simple change from clock to clock/day/date would be very appreciated. A couple of users have noted the additional value of seeing day/date around the environment in this unique time of 'shelter in place'.

I'm also interested in changing the font size. And if possible change the type of data displayed on the screensaver.
