DKPLU gets an installer

The file structure in DKP List Updater with the UIW folder and so on was causing some problems during unzipping. To resolve this I have compiled it all into a real installer that does what you would expect from your average installer. It installs the files to where you want, keeps the substructure, asks if you want to make shortcuts and such. It also adds an uninstaller options and resolves some previous problems with installing a newer version ontop of an old one.

The drawback is that it adds some extra size to the download. I hope that won't be a problem.
