Appinstall now supports standalone testing

[Austin English]

Howdy all,

I've tweaked appinstall slightly so that anyone can run it without
needing an ssh webserver to host the files. Simply do:
$ wget http://winezeug.googlecode.com/svn/trunk/appinstall/appinstall.sh
$ sh appinstall.sh

That will download all the programs and run the tests. The results
will be stored in `cwd`/appinstall-$date. Subsequent test runs of
course will have the downloads cached, so they'll be much quicker.

A couple things to note: you can change the tag name by doing:
$ sh appinstall.sh tagname

The result directory will then be `cwd`/appinstall-tagname.

Lastly, you can override the version of wine used with:
$ WINE=~/wine-git/wine sh appinstall.sh

So now you have no excuse not to test your dangerous patches before
sending to wine-patches ;-).
