Url::(en/de)code

[MartinKavik]

Add (?):

• Url::decode
• Url::decode_component
• Url::encode

Or do it automatically? How other libraries / languages / frameworks handle it?

Currently, I could use Url::path_decoded() -> Result<Vec<String>, _>. The output type could also be an iterator. Since url-decoding can fail, the error would need to be caught in some way.

I've modified routing / Url behavior a bit (PR #542, #541) - urls are automatically decoded and encoded now, including hash. Url has methods decode_uri_component and encode_uri_component that are slim wrappers around their JS counterparts. However you shouldn't need them in practice.
