ENHANCEMENT IIS 7.x no longer throws a server error if the rewrite module isn't installed when first opening the SS installer - instead, the web.config file is written with rules during installation
MINOR Tidied up installer, removing unused methods and clearly defining the web server support (from r100553) git-svn-id: svn://svn.silverstripe.com/silverstripe/open/phpinstaller/trunk@112185 467b73ca-7a2a-4603-9d3b-597d59a354a9
