Update net.kismetwireless.android.smarterwifimanager.yml source/webpage/donate url

I changed the Webasite url, since the old one pointed to a Error 404 page.

Furthermore I updated the source code url to the new one, as provided by the author: https://kismetwireless.net/downloads/#swm-git and removed the anti-feature tag. The app is still up-to-date and the SHA for the last commit under the new git url is "8ffa4f630ac9338ca63eb755ea6b8bd804e37f41" master branch.
