#2 `acpi -p -a` fails to report power state if `/proc/acpi/ac_a

[Lekensteyn]

`acpi` bases the attribute name on the file name. When using the older `/proc`, the attribute that is used to report the AC adapter state (connectd = on-line; disconnected = off-line) is either `state` or `status`.

However, acpi.c:432 does a case-sensitive comparison to Status. That will never match since the files `state` and `status` are always lowercase (at least, those lowercase files are queried). The patch is really simple, it modifies `Status` to `status`.
