Virtual files: Release mode, VIRTUAL_FILE macro

[Nielsbishere]

Virtual files should get support for the NAME macro, meaning that it shouldn't be relied on that "~/..." is a virtual path, rather something that doesn't contain slashes.
This means assumptions using the extension shouldn't be present or the path itself shouldn't be relied on, only the "name" of the path.

This means that it'd be harder to reverse it; seeing as NAME("~/My test/My example.obj") would translate to a 12 char str.

[Nielsbishere]

VIRTUAL_FILE should hash the full path, then prepend ~/. This ~/ is then removed when searching for matches.
