Add configurable time display for battery module
Adds a `format-time` configuration for the battery module so that users
can configure how they want their remaining time to be displayed.

The default format remains the same as before, i.e. `{H} h {M} min`,
but users can choose something like `{H}:{M:02d}` to give an output
like `4:29` if wanted.
