The existing windows installer looks very archaic and offers very few
configuration options. This script offers the following benefits:
* A modern appearence using NSIS Modern UI 2.0
* Shows the GPL license before install
* User can choose the target install folder
* Stores chosen installation folder in registry
* When installing a newer version on top of existing one, the existing
installation folder is offered by default
* It is possible to opt out of creating start menu shortcuts
Additional bug fixes:
* Added iconv.dll which was missing from the installer
* Replaced all path separators with backwars slashes, so that the script
works on both linux and windows
