URI query decoding.

URI query decoding.

[CrowdHailer]

Similar to #20 The specification for query parameters doesn't include nesting, however it doesn't to any degree specify what to do with multiple keys.

The solution is to write a URI2/Raxx.URI module.
Things to change:

• always return errors. URI.decode_www_form throws an error
• URI2.Query.decode() -> [{key => value}] both strings
• create a collapse to nested functionality

[CrowdHailer]

This is handled in version 0.6.0

[T-Spoon]

For anyone curious - URI2 is no longer part of this project - so decoding lists doesn't work as expected:
