eWiz 0.18.3 — Updates install themselves

Updates install themselves

eWiz no longer stops at "won't replace itself automatically" and a browser download. Each release's download is now signed, and eWiz checks that signature before installing the update in place and relaunching. An update that doesn't match is refused, and falls back to the download as before.

This takes effect from this version on: the update to it still goes through the download once.
