Major changes to command line handling and to the way we use
libdockapp, courtesy of Patrice Dumas. This should hopefully fix
several long-standing bugs with non-wmaker window managers (in
particular Debian bugs #280495 and 293546).
Updated to support newer kernels that no longer support
/proc/acpi/info - thanks to Samuel Ortiz.
Fixed a longstanding issue with redrawing - thanks to Vito
Caputo.
This version changes a number of command line options (little used
ones, but they're still incompatible changes) due to the
libdockapp work. In particular, -w becomes -x, -v becomes -V (and
takes an argument rather than being repeated), and -V becomes -v
(thanks to libdockapp grabbing -h, -v and -w for itself). Also,
long options are now supported for everything in wmacpi (but not
acpi, since it doesn't use libdockapp for command line parsing).
