Title: Add chained conversions

* The result of a conversion is fed into the next conversion with a matching file extension
* Precompiled assets on the filesystem are now treates as `Asset`s, instead of being special-cased
* The `mime-types` gem is now used to guess the MIME type of the compiled asset from the file extension
* `convert()` now takes a `String`->`String` hash, instead of `Symbol`->`Symbol`
