Various fixes/tweaks to HTTP placeholder variables and file matching

- Rename http.var.* -> http.vars.* to be more consistent
- Prefixing a path matcher with * now invokes simple suffix matching
- Handlers and matchers that need a root path default to {http.vars.root}
- Clean replacer output on the file matcher's file selection suffix
