Support wildcards URL

This PR is for adding features to the `wildcard_redirect_uri` option.

#### Features
* Support `*` anywhere in URLs. (Useful for ignoring query parameters or handle dynamic subdomains)

#### Notes
* Relies on the FuzzyURL gem: https://github.com/gamache/fuzzyurl

#### :warning: Warning
Breaking changes: add `/*` at the end of your redirect_uri to ignore query parameters like `http://mydomain.com`
Your description of this as a breaking change over the existing flag (https://github.com/doorkeeper-gem/doorkeeper/pull/437#discussion_r15276878) explains why we don't need a new option. Nevermind!
