Title: Fixes #121 (tmp/miniprofiler never gets cleaned up)

Fixes issue with ```tmp/miniprofiler``` directory filling up with files.

```FileStore``` was throwing exceptions calling ```File.mtime``` (File was resolving to ```Rack::File``` instead of ```::File```). Also, the regex was comparing against the full file path instead of its name.
