add common types to Mimetypes.java

[paleozogt]

Could we get some common mime-types added to Mimetypes.java? For example, application/json and text/yaml would be very useful.

Probably a better approach is to provide a method to let user register new mime types. What do you say?

[paleozogt]

That would also work. At the moment you have to stand on your head to do it by feeding it an InputStream. Also, it feels weird manipulating an "internal" class.

@paleozogt That's true :). I don't mind moving it out of internal if there is a valid reason. The method using InputStream isn't very helpful. I'll add a friendly method shortly. Stay tuned.

Sounds great. Thanks!

This has been added to v2.2.10 release. Please check out the release notes.
