Add warnings for charge thresholds (#679)

* add warning messages to thinkpad

* added warnings to laptop_acpi

* added warnings to ideapad_laptop

* formatted the battery output and added stats to --debug and --status

* formated --stats better with battery info

* removed blank lines in battery info

* fixed typo: --stats battery info
