Add SoC threshold for battery current limit.

[ranma]

I'd like to only limit the discharge current below a configurable state of charge (in my case currently "limit to base consumption below 70% SoC").

In principle the current limit could also be extended to support multiple SoC/voltage thresholds for different current limits, which might be useful for users of "dumb" batteries to approximate the multiple steps of discharge current reduction as the voltage or SoC approaches "empty". However currently this only adds the SoC threshold for the single current limit.

Do you thinking it’s possible to respect the „ignore SoC“ switch? (Does the switch still exist? I thought so but haven’t found it without a battery (: ) So to either hide this SoC threshold here or have a voltage threshold, when SoC should be ignored.

Added a check for "ignore SoC" and also a voltage threshold setting.
