Add ability to configure URL ACLs

User stories

• As a Setup Developer I can configure URL reservations such that I don't have to use run netsh.exe in my own custom actions.

Proposal

Create new WixHttpExtension with UrlReservation elements. These provide wrappers around netsh.exe http add/delete urlacl and their API equivalents HTTPSetServiceConfiguration and HTTPDeleteServiceConfiguration.

Considerations

This could have been added to the Util extension, but was put into the new Http extension instead.

The original proposal included support for the util:Group and util:User elements, but they had to be dropped because the custom action looks up the SID before the group or user is created.
