[slstatus][patches][limit] use different format for values above set limit

Adds a numeric limit and alternate format string to the configuration.
When the returned numeric value exceeds this limit, the alternate format
is used instead of the default one. Useful for visual alerts such as
high CPU/memory usage or low battery, e.g. by changing colors in status
bars that support it (such as dwm with color patches).
