Dashboards/Gauge: Add lower Limit key

[KreAch3R]

Hello,

I started playing around with custom gauges and noticed that the Limit option is the maximum safe upper value for the gauge created. That value also is used to create the "green" and "red" lines on the gauge, i.e. safe / not-safe values. 

I have a use-case where the minimum lower limit would make sense, i.e. everything above it is "safe" and everything under it isn't. 

Could you look into if you can implement it?

Thanks

This is the project which inspired this suggestion: https://bluewavestudio.io/community/thread-3738.html

I think it is a great example of why it's needed.

I would also like to see this. Another case use would be something like oil pressure, a warning that the oil pressure is too low.

Any official developer input on this? @BlueWave?
