[wmii] Little problem with prefix thats not in PATH

Hi,

I have set an unusual prefix for wmii and 9base. There was a little
problem because the wmii script doesn't set the PATH to include the
prefix, so it couldn't find wmiiwm. Maybe if would be wise to check if
wmii is going to be installed to any location within the path or set
the PATH to include the prefix dir. This could be done inside the wmii
script.

I'm using the patest snapshot from the wmii.de site.

Anyways, keep up the gooooooood work!
