Doug Torrance f52c697212 wmacpi: Bump to version 2.0rc1.
Source obtained from http://sourceforge.net/projects/wmacpi/files/.

2004 September 28 2.0rc1
	Added support for switching to capacity mode automatically, on
	detecting dodgy reports from the battery.

	Added support for capacity mode on charging, with automatic
	enabling as per discharging.

	Various cleanups.

	Hopefully last release before the final 2.0.

* command line tool to display current battery status, using the same
* libacpi code as wmacpi-ng.
